Prusa Extruder Rotation Visualizer Turbine

thingiverse

All design credit goes to ZekeAsakura. I modified it for my Prusa MK3s as follows: I reduced the diameter to 40mm. I trimmed the height to 10mm. I recessed a small hole to make it easier to glue in an 8mm x 3mm magnet, which I use to attach it to the extruder. I added a photo and animated GIF file. If you click "Show Original" on the first image, you will see it in action.
