3 parts profiled propeller

The main idea is to have profiled blade (at least one side on this model) easy to print. This one have 20° blades and an hand made profil. Instructions 1 - print one axle and two blade. 2 - glue together 3 - put on your favorite motor 4 - get some fresh air ;) Please make derivatives with other profil and size. Issue with this model : the blade are so thin that the profil isn't greatly printed with 0.33 layers. Category: Automotive
