Prusa Extruder Rotation Visualizer Turbine

I remixed it as follows:

Reduced the diameter to +/- 40mm
Trimmed the height to +/- 10mm
Recessed a small hole to make it easier to glue in a 8mmx3mm magnet to use to attach it to the extruder.

Printed in 0.20mm, no rafts, no supports.
Since I trimmed the bottom of the turbine off, it stuck well to the bed, as well as the bridging gives a nice surface for the glue to stick to for the magnet.
