I was inspired by https://www.thingiverse.com/thing:446442 but created this version from scratch.
It's designed to be printed in two colors with a manual filament change in the middle. It also has a provision for mounting on a nail.
The openscad source is included, mostly because if you have a multi-extruder setup you'll probably need it if you want to prepare a version that automatically prints in two colors.
Supports: No
Infill: 10%
Infill and resolution don't matter a great deal. I actually printed it at 50% scale.
Use PrusaSlicer's color change at layer function, or just pause the print at the appropriate height and change the filament from black to white. This is at 3mm in the full size model or 1.5mm in the model at 50% scale.
The author marked this model as their own original creation. Imported from Thingiverse.
