Thanks for downloading!
We'd love to hear from you if the print was successful.
Windmill-powered music box
This is a little windmill which powers a music box: You can set it up in your garden or on your balcony and every time the wind blows, you'll hear some nice music!Art

- Printed on:
- prusa i3 mk3
- Good print at first try with Prusa Lime Green EasyABS. With only minor irregularities. I've also opted to print the blades themselves, in Extrudr PET, to add more colour. I've traced the png in Inkscape, exported the result to OpenSCAD, where I intersected it with a large cylinder to have a slight curve on one side of the blades.
