Finally here it is: the “Version Zero” of a printed paper windmill. One day I would like to upload another version (you can see it in one of the pictures) but, while it woks, the wings still have too much issues... we'll see.This thing, as provided here requires little wind to start its movement and very little wind to keep on spinning. It's not made to be efficient but just a toy. Do use the OpenSCAD (good luck) to make it bigger, better, nicer!There are some pictures here: flickr.com/photos/aubenc/sets/72157629199542154/And (not that) a short video here: youtube.com/watch?v=cjXmF2cNxVgI wrote a lot (my apologies) in the PDF so I'll keep it short here.Print in 3 different colors, assemble and have fun!The zip file contains more STL for wings with different thicknesses and threaded parts with different tolerances.Think it twice before deciding to use the producion plates! bot1334 required different setting for the wings and the threads.(sorry but it has to be said...)Be aware that this thing can spin really fast and thus can produce damages or hurt somebody whenever it breaks, something gets loose or not. I take no responsibility if something goes wrong.
