Wind Turbine Extruder Indicator

This is a little extruder indicator in the shape of a modern wind turbine. I was inspired by the Dutch-style windmill extruder indicators in Prusa's video here:

To attach to your motor, you will need either two 8 x 3 mm disk magnets or a single 8 x 6 mm magnet. I used two 8 x 3 mm magnets like these: https://www.aliexpress.com/item/32858924730.html

I used some Loctite brand superglue to attach the magnets to the printed part.

Print instructions

This part can be printed in about 6 minutes on my Prusa MK3S using a generic PLA or PETG profile, but I would strongly recommend reducing your print speed as low as 20% to get the best quality part. Still prints in about 30 minutes even at slow speed.

Reducing speed helps a lot - the blue part was printed at 100% speed, while the white part was at 20% speed. I printed in white Overture PETG at 0.15 mm layer height using the Generic PETG profile in Prusa Sliver, but PLA would work just as well. Included gcodes are at 0.10 mm layer height, but you should use the Tune menu to reduce speed at the beginning of the print.
