Involute VAWT

A small vertical axis wind turbine. The turbine itself is printed in two halves and glued together using 4" long wooden dowels (not sure of the diameter off hand). The shaft is 6mm in diameter and 100mm long. There is a 6mm ID x 10mm OD x 10mm long bronze bushing pressed in near the top and a 6mm ball bearing pressed in near the bottom. The assembly mounts to the end of a 1" EMT conduit. No generator for this design yet. The cone has some support material that has to be removed. I used a small file to smooth out the bumps left over from removing the three legs.
