Mubot Extruder Spinner
thingiverse
Mulbot Extruder Spinner Secure an 8mm diameter x 3mm thick magnet to the back of your extruder motor with super glue, then attach it to the motor. This will cause it to spin as the motor rotates. I created this design with my kids in mind, initially planning for it to be a pencil topper. However, I later adapted it to function as a Mk8 extruder spinner and have since modified it to accommodate my new Mk3.
