I’ve spent hours on Thingiverse, Printables and Cults 3D trying to find a FREE (sorry, work at a small public library) wind catcher or moving art wen could 3D print and hang in outside garden but I haven’t had much luck. Perhaps, there are other free 3D print sites you would please suggest?
The theory behind these wind driven pieces is you are creating an air foil. The wind catches the “wing” and moves it around. You need a good bearing at the top to keep from just winding up the string. A simple washer and loop is needed to isolate the sculpture and the hanger.
I don’t understand, You claimed you couldn’t find a free version on Thingiverse, and I posted what I found there. I did not create that model, nor do I plan to print it out.
