A print flat design. Makes a 368 mm twin blade from 198 mm parts. Power that little dude chopping wood or any other thingy with the wind. Simply bolts... together.
Prints without support. Use this to power your garden gadgets and decorations. All parts fit on a 200 mm print bed. If you have a larger bed or want to print a longer one on the diagonal mod the Sketchup file by using the push/pull tool on the end of the wing. I may make a 3,4 and 5 blade version later. This was a bit of a pain to model so don't expect it anytime soon.
