Carousel thumb windmill
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.
