Profile

Ribs

Joint

One point per line: radius, height. Lowest first. Catmull-Rom interpolated.

Outer profile

\n \n

Inner bore

Bore mode\n \n

Bore radius\n

\n \n

Floor thickness\n

Helical thickenings for vase-mode rigidity. Outer ribs add visual interest; inner ribs grip a bottle.

Count\n

Depth (mm)\n

Width (mm)\n

Side\n \n

For two-piece vase prints. The bottom's top tapers inward; the top's bottom tapers outward. They wedge together over an overlap zone.

Mode\n \n

Overlap (mm)\n

Taper (mm)\n

0.3–0.5mm taper over 15mm typical. Tighter = stiffer fit but riskier slip-through.

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). The XY accuracy of an A1 Mini is sensitive to\n these.\n\n## Reference test ring file\n\n`examples/pressFitTestAll4.ts` — 2×2 grid of four 11mm-tall test rings\n(short version, position-coded by quadrant on the build plate). Print to\nre-calibrate any time the printer or filament changes.\n\n## Shipped values\n\nThe 0.5L mini sleeve V2 Bottom uses **Tight fit** (PLUG_OD 69.90 against\nSOCKET_ID 70.0 in the V2 Top). See
