Geometry:
- Outer diameter (OD): Ø 18.00 mm
- Inner diameter (ID): not specified (solid or define wall thickness if hollow)
- Total length: 40.00 mm
- End faces: flat, sharp edges (recommend edge break 0.2–0.5 mm)
Manufacturing: 3D printed or machined (depending on material/requirement)
Tolerances (typical):
- General: ±0.20 mm (FDM printing) / ±0.05 mm (machined)
- Roundness/cylindricity: as required
3D printing notes (if applicable):
- Print orientation: tube axis along Z-axis → maintains circularity of bore
- Perimeters: ≥4; infill 20–40% (if hollow, perimeters dominate strength)
- Holes/fits: allow +0.1…0.3 mm clearance for proper fit
