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",[],[447],"1f7787ae-4636-11f1-9542-42b51c65c3df","types.ts","1f778880-4636-11f1-9542-42b51c65c3df","c9b45804-cc24-42a7-b676-96849237af3f",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",[],[464,456],"vase-creator","510dd55c-4636-11f1-b372-42b51c65c3df","510dd5f2-4636-11f1-b372-42b51c65c3df",270,["D",1777733452714],"/**\n * CSS for vase-creator.
