A little windmill for the Creality Sprite Extruder. Glue a 6.35mm x 1.53mm magnet in the back. 

The walls are designed on an intervals of 0.4mm to help with printing on a 0.4 nozzel. The print is still finnicky to stick the first layer.

The design is visually based off https://www.printables.com/model/183664-windmill-stepper-visualizer , but redrawn.
