A simple key chain pill box in OpenSCAD, so you can size it to your needs.
Download OpenSCAD (opensource, Win/Mac/Linux), load the scad file and customize the values on the right side. Press F6 for render and F7 to export as STL.
Printing: 0.4mm nozzle, standard settings. I use octagonal spiral bottom infill for a decorative effect.
The author marked this model as their own original creation.
