Designed for use with the Makelangelo polargraph project!
It should be compatible with Werner's penholder for the gondola.

These are IKEA SKÅDIS compatible NEMA17 motor mounts for use in a polargraph machine. The mounts include a tab for an endstop that are hit by the counterweights. There is also a notch to ziptie the cables down.
The design was made with the goal of using the SKÅDIS pegboard as an easily adjustable polargraph with preset belt and board measurements.
The counterweights use NEMA17 steppers as a low-effort option. Admittedly they're not centrally balanced but work well enough. The two 42x42x34 counterweight motors balance nicely against a single 42x42x58 gondola motor as in Werner's penholder design. The space between the endstop and motor body is a bit tight, so you might need to bend the legs of the endstop to fit.
The project converted an Ender 3 into a Makelangelo-based polargraph reusing all the motors, PSU, and the GT2560 mainboard running marlin-polargraph. You will need to buy new, longer 6mm belts if you want to maximize the drawing space.
PM me if you need help on configuring the firmware for this kind of project.
