Parametric Friction-Fit Cap
thingiverse
Parametric friction-fit cap made in OpenSCAD by a beginner. Made ultra tight for my application as I mistakenly opened the peel side of a grease tube rather than the capped end and do not want to ever come off. To size for your application: capD: Measure OD of protrusion on container, add 2x your cap outer thickness, add tolerance so binding band can slip by. bbTD: measure distance from top of container to bottom of container protrusion, add tolerance.
