Summary

This is a 3D-printable motor pulley to replace the stock one on a Dreaming Robots Electric Eel Wheel Nano. It'll work with either the v1.0 or v1.1 motor, and you may need a drop of CA glue to secure it to the motor shaft.

This is the pulley that I sell on my website.

Post-Printing

Afte printing, remove supports with pliers. You should be able to grab the supports sticking out the side and pull them out. Go around the pulley with a sharp tool to scrape out any remnants inside the groove.
