Description

Fun stepper motor motion visualizer for your Prusa MK3S stepper motors.  Provided keys are scaled for Prusa i3 MK3 series printers.  Can be used (scaled to fit, if necessary) with any printer's stepper motors.  Models are provided sized to fit on E, X, Y, and under Z stepper motors.  Should work fine on MMUs as well (feedback anyone?).

If you have a MK2 and print these out, let me know if they work for you.

Print instructions

Download.  Slice.  Print two halves for each stepper motor desired.  Assemble halves with CA glue (make sure base is flat).  Attach magnet with CA glue (make sure magnet is centered).  Affix magnet to stepper motor axle.

Supplies

8mm x 3mm neodymium magnets (100-pack)

Cyanoacrylate (super) glue (your favorite flavor, try Harbor Freight for a cheap source)

Summary

A turn key (Bob-omb, skate key, radiator key) styled stepper motor motion visualizer.  Print both halves, glue them together, glue an 8mm x 3mm magnet onto the end, (let dry,) affix to the exposed axle on the end of the stepper motor, enjoy.  Thanks to Miketastic and holabaloo for the inspiration.
