All values are PLA on a\nBambu Lab A1 Mini with **fuzzy skin enabled** (0.4mm distance / 0.3mm point\ndistance) on the test rings.\n\n## Tolerance ladder\n\n| Fit category | PLUG_OD | Radial clearance | Diametric clearance | Behavior |\n|----------------|---------|------------------|---------------------|----------|\n| Slide fit | 69.70 | 0.15mm | 0.30mm | Drops in, freely separates |\n| Loose fit | 69.80 | 0.10mm | 0.20mm | Seats with light pressure, can be twisted apart |\n| **Tight fit** | **69.90** | **0.05mm** | **0.10mm** | **Hand-press required, holds securely (chosen)** |\n| Semipermanent | 70.00 | 0.00mm | 0.00mm | Hammer/clamp to seat, won't separate without damage |\n\n## How to use this for other parts\n\nTolerances are **relative to the socket ID** — they're not absolute numbers.\nTo pick a PLUG_OD for a different socket:\n\n```\nPLUG_OD = SOCKET_ID − (2 × desired_radial_clearance)\n```\n\nSo for any socket dimension, the recipe is:\n\n| Target fit | Radial clearance to subtract from socket radius |\n|------------------|--------------------------------------------------|\n| Slide fit | 0.15mm |\n| Loose fit | 0.10mm |\n| **Tight fit** | **0.05mm** ← default for sleeve joints |\n| Semipermanent | 0.00mm |\n\nExample for a 50mm socket: tight fit plug = 50.00 − (2 × 0.05) = **49.90mm**.\n\n## Caveats\n\n- **Fuzzy skin matters.** Fuzzy adds dimensional bumps that slightly\n *reduce* effective fit (the bumps deform under press pressure). Without\n fuzzy skin you may need to add ~0.05mm to the plug OD, or test on a\n smooth ring first. These numbers were calibrated WITH fuzzy on.\n- **Printer matters.** A1 Mini was used. Other printers (Prusa, Ender,\n Voron) will likely need re-calibration — XY shrinkage and belt tension\n vary by machine.\n- **Material matters.** PLA only. PETG is stickier and tends to need\n ~0.05mm more clearance for a comparable feel; ABS/ASA shrink more so\n you may need less.\n- **Plug height matters.** Test rings used PLUG_H = 3mm. Taller plugs\n generate more friction along their length, so a \"tight\" plug at 3mm may\n feel \"semipermanent\" at 10mm. For deep press fits, drop one category\n (e.g., use Loose dimensions for a 10mm-deep plug to get Tight behavior).\n- **Plug wall thickness matters.** Thin plug walls (under ~1mm) flex\n inward under press pressure and feel looser than they measure. The test\n rings used a beefy 1.85mm plug wall. The shipped sleeve uses 1.4mm.\n Thinner than ~1mm = unreliable; consider thickening before re-tuning fit.\n- **Re-test if you change print settings** (line width, wall count,\n flow rate, layer height).

Diffuser tests use 60 × 30 mm coupons, preserving the centered\n 50 × 20 mm optical area and testing 0.20 / 0.40 / 0.60 mm face thickness.\n- Optical test protocol: print every coupon **visible-face down**, evaluate the\n build-plate side, and disable ironing. Keep filament, build plate, first-layer\n height, nozzle/bed temperatures, flow, speed, and cooling identical between\n coupons and final enclosure; STL cannot encode these slicer settings.\n- Coupon result (2026-09-07): Charlie selected **level 2**, so the enclosure\n defaults to `FACE_LAYERS = 2` at 0.20 mm layers, for a **0.40 mm** translucent\n front membrane. Level 1 (0.20 mm) and level 3 (0.60 mm) remain explicit\n alternatives; do not silently change the selected default.\n- Official product page: https://docs.m5stack.com/en/unit/digi_clock\n - Published product size: 50 × 31 × 14 mm.\n - Four mounting holes/tabs; official product photo labels the slots 3 × 4 mm\n and a 32 mm horizontal mounting-center relationship.\n - Official photos show mounting ears projecting beyond the display fascia and\n Grove connectors at both short ends. **Do not** use a plain 50 × 31 mm box as\n the fit pocket or assume the published envelope fully covers projections.\n- Enclosure geometry must keep separate parameters for fascia/body, tab projection\n and width, four hole locations, Grove connector bodies, plug insertion clearance,\n and cable bend/routing space. These remain provisional until physically measured.\n- Controller: **AtomS3 Lite, SKU C124**, official envelope 24 × 24 × 9.5 mm\n (official STL measures 24 × 24 × 9.507 mm). USB-C is centered on one edge.\n Source: https://docs.m5stack.com/en/core/AtomS3%20Lite\n- Charlie selected **Concept A**: a low, squat, elongated ellipsoid / rounded\n soap-bar body whose angled display face remains separate from the broad,\n horizontal stable base. Do not continue or present the overlapping Concept B.\n- The reviewed A envelope is approximately 124 × 84 × 48 mm in use. The display\n plane remains tunable at 55° and the exported model is automatically reoriented\n so the 0.40 mm visible clock face prints flat on the build plate.\n- The active U146 Grove port is on the **left when viewed straight at the display**.\n The plug insertion, bend pocket, Atom route, and service access must remain\n inside the shell; no side opening is allowed. The passive right connector body\n must remain internally accessible.\n- Enclosure exterior finish is slicer-only: Bambu fuzzy skin thickness **0.10 mm**\n and point distance **0.10 mm**, painted only onto exposed curved exterior side\n walls. Exclude the translucent membrane/build-plate face, stable flat base,\n internal pockets/cradles, Grove connector and cable-bend reliefs, USB-C notch,\n service-opening rim, and all mating/retention surfaces. Do not apply this\n setting to the diffuser coupon plate.\n- Concept A is **not yet print-ready hardware**. The official 50 × 31 × 14 mm U146\n body envelope and 24 × 24 × 9.5 mm AtomS3 Lite envelope are represented, but\n the U146 ear projection/width/vertical centers, real left Grove plug overmold\n and bend envelope, USB-C center/overmold/insertion space, rear closure, display\n and Atom retention, assembly order, and local wall thickness around all cuts\n still require measurements or decisions. A slicer overhang/support review and\n an exported-mesh repair/manifold check are also required before print approval.\n\n### Traveler guitar → printed SKÅDIS adapter\n\n- Traveler guitar has two nominal Ø6 mm rod/hole locations.\n- Charlie measured 60 mm maximum outside-edge span across the two holes, not\n center-to-center. The current concept therefore infers 54 mm nominal centers;\n confirm with calipers before a fit print because both the diameter and span are\n approximate.\n- The SKÅDIS board plane contains the guitar rod axes and is perpendicular to the\n guitar's hole-opening plane, so the adapter is a 90° L-shaped transition.\n- Charlie's 3D-printed SKÅDIS slots run tight. Start with deliberately undersized\n test keys (current concept 4.20 × 9.20 mm) on 40 mm pitch rather than assuming\n official IKEA fit.\n- Current direct concept requires two assembly motions: approach normal to the\n board far enough to insert the hook caps, then slide about 4 mm in-plane to\n lock. Confirm the guitar/body leaves room for both motions and choose the slide\n direction before making this print-ready.\n- Current provisional board thickness is 5.0 mm. Measure the actual printed slot\n width/length, board thickness, rod OD, desired board offset, available insertion\n clearance, board/amp load, and orientation before final design.\n- If direct insert-and-slide clearance is blocked, prefer a two-piece design:\n standard SKÅDIS hooks on a board-side cleat plus a separate guitar-side\n dovetail/rail. That decouples board installation from attachment to the guitar.\n- Editable concept id: `travelerSkadisAdapterConcept`; presentation slug:\n `traveler-skadis-adapter`. It is a motion study, not print-ready hardware.\n- Hole-fit matrix printed 2026-09-12 in the active Bambu A1 Mini PLA Wood\n profile: nine 72 × 20 × 1.20 mm coupons, no brim/support, 0.20 mm layers.\n Left-edge notch count encodes centers: 1 = 53.5 mm, 2 = 54.0 mm,\n 3 = 54.5 mm. Right-edge notch count encodes bore diameter: 1 = 6.15 mm,\n 2 = 6.35 mm, 3 = 6.55 mm. Charlie selected **2 left notches / 3 right\n notches**, confirming **54.0 mm nominal centers and Ø6.55 mm bores**.\n Example id: `travelerHoleFitTestPlate`.\n- Equal-spacing plates steal the bent rods' spring/friction tension. Keep the\n fixed Ø6.55 mm bore and use the outward capsule slot from\n `travelerReliefSlotTest`: 54.0 mm inner-center position with 10.0 mm outward\n center travel (54–64 mm relationship).\n- KOKKO KG-10 cradle clearance matrix result (2026-09-12): **only the loosest\n 99 × 67 mm profile fit at all, and it still required flexing**. Treat that as\n the minimum measured envelope, not the basket size. The shallow basket study\n uses a provisional **101 × 69 mm internal opening** for non-press-fit seating.\n Its 101 mm direction runs backward and its 69 mm direction runs outboard so\n the integrated 159 × 126 mm study fits the A1 Mini bed. Do not revert to the\n 97.5 × 65.5 or 98 × 66 openings.\n- The amp holder is a **coplanar tray/basket**, not an upright side-profile ring:\n its full floor shares the rod plate's plane and shallow walls rise normal to\n that floor. Direction convention for the integrated model is **negative X =\n outboard beyond the guitar butt** and **positive Y = behind the guitar**; do\n not offset the basket forward. The low placement/fit preview is deliberately\n built as one 4 mm carved solid with a 1.20 mm basket floor, 2 mm wall width,\n and 2.8 mm of wall above the floor. Its rod plate and basket are connected by\n a broad smooth fan, not a narrow diagonal neck or overlapping separate bodies.\n Reserve the available 30 mm behind-guitar height for later curved ribs/gussets.\n Intended final load version remains approximately 10 mm at the rod plate and\n 20 mm-high basket walls, after placement and clearance are confirmed.\n\n## Presentation views\n\n- For TVs, embedded reviews, and visual approval, use the control-free route\n `/present/`; never embed the full STL Creator editor.\n- Presentation views must reuse the registered example's `generatorBody`, fill\n the viewport, auto-fit the whole part after resize, and leave the editable\n root editor route unchanged.\n- Add a model to `PRESENTATION_MODELS` in `main.ts` with its title, note,\n generator body, and optional in-use pose correction. Supported query options\n are `pose=in-use|print`, `labels=0|1`, `background=RRGGBB`, and\n `accent=RRGGBB`. The legacy `/preview/` route is an alias.\n- For the DigiClock enclosure, use\n `/present/digiclock-enclosure-a?pose=in-use` for the selected Concept A;\n print pose is only for fabrication inspection.\n\n### Bottles / sleeves (foot diameters that matter for base clearances)\n\n- 0.5L mini sleeve foot: Ø84 (waterSleeveMiniV2Bottom)\n- 1.5L sleeve foot: Ø114 (waterSleeve15V2Bottom)\n- 5L jug: superellipse a=90 n=2.67 (~180 flat / ~196 diagonal)\n",[],[488],"1f7787ae-4636-11f1-9542-42b51c65c3df","types.ts","1f778880-4636-11f1-9542-42b51c65c3df",266,["D",1777733369515],"/**\n * Shared types for vase-creator.\n */\n\nexport type Pt = [number, number]; // [radius, height]\n\nexport interface Cfg {\n filename: string;\n points: Pt[];\n boreMode: \"constant\" | \"profile\" | \"none\";\n boreRadius: number;\n innerPoints: Pt[] | null;\n floorThickness: number;\n ribCount: number;\n ribDepth: number;\n ribWidth: number;\n ribSide: \"outer\" | \"inner\";\n splitMode: \"none\" | \"bottom\" | \"top\";\n wedgeOverlap: number;\n wedgeTaper: number;\n}\n\nexport interface Preset {\n name: string;\n points: Pt[];\n boreMode: \"constant\" | \"profile\" | \"none\";\n boreRadius: number;\n innerPoints: Pt[] | null;\n floorThickness: number;\n ribCount: number;\n ribDepth: number;\n ribWidth: number;\n ribSide: \"outer\" | \"inner\";\n splitMode: \"none\" | \"bottom\" | \"top\";\n wedgeOverlap: number;\n wedgeTaper: number;\n}\n",[],[198,497],"510dd55c-4636-11f1-b372-42b51c65c3df","510dd5f2-4636-11f1-b372-42b51c65c3df",270,["D",1777733452714],"/**\n * CSS for vase-creator.

Use when designing or tuning any mating dimension in this stl-creator val (caps, plugs, sleeves, grooves, bores, the bokashi bin parts), or whenever a printed part \"won't fit / too loose / too tight / pinches / leaks / won't stop.\" Pairs with PRESS-FIT-NOTES.md.\n---\n\n# FDM fits & seals — A1 Mini, PLA\n\nEmpirical, machine-specific. All numbers assume **Bambu A1 Mini, PLA**, and (for the static ladder) **fuzzy skin on**. Re-calibrate if printer/material/settings change. The authoritative static-press-fit ladder is in this val's `PRESS-FIT-NOTES.md`; this file adds the seal/thread/slide/orientation learnings on top.\n\n## 1. Static press-fit ladder (plug into a socket)\n\nRelative to the **socket ID** — subtract this radial clearance from the socket *radius* to get the plug OD:\n\n| Fit | Radial clearance | Behavior |\n|---|---|---|\n| Slide | 0.15 mm | drops in, separates freely |\n| Loose | 0.10 mm | seats with light pressure, twists apart |\n| **Tight** | **0.05 mm** | hand-press, holds — default for sleeve joints |\n| Semipermanent | 0.00 mm | hammer/clamp, won't separate undamaged |\n\n`PLUG_OD = SOCKET_ID − 2 × radial_clearance`. (e.g. Ø50 socket, tight plug = 49.90.)\n\n**Modifiers:**\n- **Plug depth matters a lot.** Calibrated at 3 mm deep. A \"tight\" plug at 3 mm feels \"semipermanent\" at 10 mm+. For deep plugs, **drop one category** (use Slide dims to get Tight behavior at ~12 mm). The bokashi top uses a 0.30 mm *diametral* (slide) plug at 12 mm and that reads as a secure-but-removable press.\n- **Thin plug walls (<1 mm) flex inward** and feel looser than they measure; keep ≥1.4 mm.\n- **Fuzzy skin** was on during calibration; without it add ~0.05 mm to the plug OD.\n\n## 2. Diameter affects the fit\n\nGood press fits have been hit at very different diameters (PET 0.5 L sleeve ~Ø70, 5 L cap ~Ø48), but **the same absolute clearance does not transfer perfectly across diameters** — bigger circles carry more ovality / tolerance stack, so larger-Ø fits tend to want a hair more clearance. Treat the ladder as a starting point and **re-test at the actual diameter** (print a quick ring ladder: `examples/pressFitTestAll4.ts`).\n\n## 3. O-ring / gasket seals (dynamic, piston-style)\n\nHard-won on the bokashi plunger (Fortlev DN100 esgoto ring, round bead, measured **CS = 6 mm**; ID measured by gauge ring = **106 mm**):\n\n- **Retention comes from the ring's ID stretched on the groove ROOT** (hoop grip), not from cradling the cross-section or a \"backstop\" wall. Set `groove_root_dia ≈ ring_ID × 1.02` (~2 % stretch). A backstop wall can't help much: it can't reach over the bead's crown without poking out to the bore diameter and rubbing.\n- **Groove cross-section clearance: ~0.3 mm radial** (`groove_tube_radius = bead_radius + 0.3`). FDM concave grooves print **undersized**, so 0.1 mm prints as a *pinch* that clamps and bunches the bead. Never go below ~0.3.\n- **Squeeze%** `= (seated_OD − bore) / (2 × CS)`, where `seated_OD = groove_root + 2 × CS`. 0 % squeeze is at `bore = seated_OD`.\n- **Sealing vs sliding is a genuine conflict.** Airtight wants ~15–30 % squeeze; easy sliding wants ~10–15 %. ~33 % is a firm static seal but high insertion force. You can't get both in one *traveling* seal.\n - **The fix: decouple.** Make the airtight seal **static** (a lid/rim that doesn't travel through gunk) and let a separate **non-sealing follower** do any pressing/sliding. Reuse the same O-ring work as the static lid gasket.\n- **Lube** lets a too-tight ring slide much further than dry, but don't design around it (especially food/compost — it goes rancid / gets absorbed). If it needs lube to slide, the squeeze is too high.\n- **Printed bores leak/drag along layer lines.** A vertically-printed bore has horizontal ridges the bead must cross. For a *true* dynamic seal, prefer a smooth bought tube (acrylic/PC) and print only the piston.\n\n## 4. The \"ID sweep\" — guarantee a part stops/seats at a height\n\nTo make one part **park at an approximate height** inside another, taper the bore so it narrows **below** the mating diameter. The part slides through the loose section and physically cannot pass the point where bore < part. Approximate but self-guaranteeing; tune the park height with the taper rate / bottom diameter. (Bokashi bin body: Ø120.7 main bore → Ø114 over the last 60 mm parks the collector ~3–4 cm up.)\n\n## 5. Screw threads (PET / PCO-1881 reference)\n\n- Method: trapezoid thread profile stamped along a helix + `hullChain` (no native helical sweep in JSCAD 2.x). See `examples/petBottleCap.ts`.\n- **PCO-1881 real dims:** T = 27.40, E (root) = 24.94, pitch 2.70, single-start RH, 40° thread, ~1.8 turns (650°). Getting E right matters — too deep bottoms the cap on the bottle's neck core.\n- **Clearance 0.30 mm radial.** Female (cap, fits a real bottle) = nominal **+** clearance; male (neck, a real cap fits) = nominal **−** clearance.\n- Beef thin-looking threads by **crest width** (0.3 → 0.5 mm) and wall, not depth (depth is set by the mating part).\n- Handedness: the helix is cut RH; if a real part threads backwards, negate `theta` in `makeThread`.\n\n## 6. Overhang / orientation (so fits print true)\n\n- Walls within ~45° of vertical print without support. A bore that **widens going up** is self-supporting; one that **narrows going up** overhangs.\n- Funnels/tapers need height to stay steep: Ø115 → Ø34 needs ~46 mm to keep the inner wall ~38° from vertical.\n- Round O-ring grooves print with a small top-lip overhang — acceptable minor sag; don't \"fix\" it by deleting the lip (that drops bead wrap and retention).\n- Caps print best ceiling-down (open end up); model print-ready or note the flip. A 180° flip preserves thread handedness (rotation, not mirror).\n\n## 7. Quick workflow when a fit is off\n\n1. Wrong size? **Gauge it empirically** — print a thin nested ring ladder (ID gauges to find a diameter, bore gauges to find squeeze) rather than trusting a spec. Cheap grams beat a re-print of the real part. (See `examples/seal-test/sealSizers.ts`.)\n2. Too tight / pinches → add clearance (≥0.3 for grooves; up a ladder category for plugs).\n3. Too loose → for O-rings, increase root stretch (not cross-section); for plugs, drop a clearance category.\n4. Won't stop / creeps → use an ID-sweep taper or a hard ledge.\n5. Always re-test after changing line width, walls, flow, or layer height — A1 Mini XY accuracy is sensitive to these.\n",[],[577,578,570],"skills","fdm-fits-and-seals","58d9e688-78b3-47af-8bff-72728b00624a","019fbdae-2552-7012-a355-37189bf7953e",["D",1785593734484],[389],[577,578],"f71e9c50-db54-4c92-891b-dfc9cce58a5c",["D",1785593734484],[388],[577],"ee3e0e54-398f-4b73-9bb8-f8d754f2f37a","woodGrainWallSampler.ts","a599bc40-a427-11f1-8293-1607ee4eb77e","019c3dc4-fdf2-76fa-8252-909c6fe161f6",471,["D",1788064248700],4,"import type { Example } from \"./types.ts\";\n\n/**\n * Wood Grain Wall Sampler — four nominal 1-inch square faces.\n *\n * Four distinct directional grain treatments are modeled into the STL.\n * The fourth face uses discrete vector-style relief paths, like projecting\n * SVG strokes onto a face, rather than a slicer texture.\n *\n * PRINT: upright, ordinary mode (NOT spiral vase), 0.16–0.20 mm layers,\n * 3–4 wall loops.

With cap top on plate:\n * - First layer is an annular ring r=18..r=42 (= 24mm wide) — excellent\n * adhesion, no brim needed.\n * - Cone outer becomes anti-overhang (wall narrows as printer climbs).\n * - The only bridge is at the narrow-to-wide inset transition (model z=23):\n * 8.5mm radial bridge, well within Bambu A1 Mini's 15mm clean-bridge limit.\n * - Thread lead-in flank is supported by tooth body below; load flank is\n * supported by helical neighbor on previous turn.\n *\n * Test procedure:\n * 1. Print and let cool. (~30 min on Bambu A1 Mini.)\n * 2. Thread onto your 5L jug. Should engage cleanly with triple-start\n * (12mm cap descent per full rotation).\n * 3. Drop the vessel into the top inset. Should slip in with light play,\n * narrow section disappearing into the cap interior.\n * 4. Hang the full assembly (5kg) by a paracord through the bore — verify\n * the buttress threads hold.\n *\n * If the vessel doesn't fit: measure its actual dimensions and tell me;\n * I'll adjust `wideInsetR` and `narrowInsetR`.

Single thread end → single-start (this design).\n * Two ends 180° apart → double-start; rebuild needed.\n * - Profile: shine a light sideways. Symmetric rounded → fine. Asymmetric\n * buttress/sawtooth → needs custom profile.\n *\n * If threads bind: increase `clearance` from 0.30 to 0.40, or reduce\n * `threadDepth` from 1.6 to 1.5. Reprint just this part (small, ~30min).\n *\n * ⚠ PRINT UPSIDE-DOWN: flip in slicer so disc-top is on the build plate.\n * This puts the disc-bottom flange (pressure surface against bottle rim)\n * facing up = fully supported, smooth surface finish.\n */\n\nconst example: Example = {\n id: \"cap5L48mm\",\n icon: \"🧢\",\n name: \"Cap — 5L 48mm PET Donut\",\n desc: \"[2026-05-02] Twist-on cap for 5L PET jug (48mm coarse thread).

Three helical grooves + three full-height\n vertical **gates** are cut inside it.\n- Every opaque segment carries a ring of **3 studs** (Ø6, 2.2 proud, 12mm\n below its top). Studs are docking stations.\n- **Dock**: drop the shade so a stud ring enters the gates, twist — studs ride\n the helix, shade screws down. Lead 45mm/turn ≈ 7° helix → self-locking, the\n shade parks at ANY height in its 75mm of travel. Twist back + lift = off.\n- **Lantern mode**: dock at the CROWN studs, shade up → plant + ring enclosed\n in yellow glow, the whole thing reads as one closed cylinder.\n- **Plant mode**: lift off, drop to the BASE (or riser) studs → shade becomes a\n low yellow band, plant + ring fully exposed.\n- The gates run the full band height so the shade can slide PAST upper stud\n rings to reach lower docks. **Rule: keep stud rings >92mm apart vertically**\n (base 103 / riser 103 / crown 120 all satisfy this — don't shorten them).\n\n## Height adjustment as the plant grows\n\n1. Fine (0–75mm): twist the shade up its track; extend the telescopic pole to\n keep the ring near the shade top.\n2. Coarse (+100mm per): print another RISER, pop the stack apart at any\n press-fit joint, insert, re-dock the shade at the crown.\n\n## ⚠ MEASURE FIRST (calipers, before printing the big parts)\n\nBokashi rules apply — the light's dims are unpublished.

Feed the cord's plug down through the crown keyhole, then (after stacking)\n through the base floor slot and out the under-floor groove — the tower sits\n flat on top of it; cord leaves at ground level, invisible.\n2. Seat the pole in the base socket (it bottoms out at z=6).\n3. Hang the bottle in the crown plate (twist-top catches the Ø29 hole), press\n the crown onto the base (riser between, if any).
