Parametric Twist-Lock Cylinder Container

A heavy-duty, tactile twist-locking canister engineered with dual-bayonet locking lugs. Perfect for waterproof pill cases, travel organizers, hardware fastener containers, or custom cylindrical enclosures.


⚙️ Key Parametric Variables

ParameterDefaultRangeDescription
inner_diameter40mm15mm - 150mmUsable inner diameter of the cylinder cavity.
inner_height60mm20mm - 250mmInternal depth of the lower storage chamber.
wall_thickness2.4mm1.2mm - 5.0mmShell thickness (recommended 3+ perimeters).
lug_tolerance0.35mm0.15mm - 0.6mmClearence gap between the bayonet lugs and lid tracks.
knurl_density240 - 64Number of radial grip flutes on the container lid.

🖨️ 3D Printing Recommendations

  • Material: PETG or PLA+ (PETG provides optimal layer adhesion and flex for locking lugs).
  • Layer Height: 0.16mm or 0.20mm for smooth bayonet ramp engagements.
  • Perimeters: 3 - 4 walls (ensures strong solid lugs without needing infill support).
  • Infill: 15% - 20% Gyroid.
  • Supports: None required — bayonet entry chamfers are engineered at 45° overhang angles.
