Sometimes I need a lid for a can, so I made one. It's parametric and customizable in OpenSCAD, so you can adapt it to your needs. It snaps into place and is easy to open.
Customizing:
- Measure the diameter of the can's rim (in mm).
- Download and install OpenSCAD (Win/Mac/Linux; it's free and open source).
- Start OpenSCAD and load the scad file.
- Change the value for D (diameter of can rim, mm) in the customizer on the right side accordingly; the other values are probably fine.
- Press F6 to render, then F7 to export as STL.
