MPCNC springy pen for drawing

thingiverse

A springy pen for the MPCNC makes drawing a breeze. I printed the holder and carefully inserted the pen cartridge along with its spring. To secure the cartridge's spring, I used a small cable tie on top. Two more cable ties were then applied to the tool mount, ensuring the housing was in place without restricting the cartridge's movement or getting caught. This setup allows for smooth drawing on uneven surfaces.
