2 Blade Wind propeller

thingiverse

What you need to print: 1x P1 2x P2 2x P3 (either V1 or V2) A screw should be driven through the center hole to spin it, because plastic is too fragile as shown with the previous three-blade wind propeller. I also used a drill to spin it, but any motor will do. The difference between P3 V1 and P3 V2 lies solely in size. Unfortunately, I was unable to print V1 due to its excessive dimensions, so I created V2, which is smaller. You can choose either one, but you must print the same quantity (you cannot print 1x V1 and 1x V2). I used hot glue to assemble the parts together; that's what the connectors on the bottom of the wings are for.
