Leapfrog Creatr pen holder plotter drawing addon

This is a little part I made to attach on my printer's extruder cartridge, and be able to use it as a plotter.
Compatible with Leapfrog Creatr dual extruder.
A rubber band and a pen refill tube is needed in order to use it.

You may need to add some tape around the refill, to make it fit a little tigther in the hole, if it moves around too easily.
