Wind turbine / Windmill

This is my Model of a Wind turbine. For the rotation you require a ball bearing 608 (8x22x7 mm). I have chosen the dimensions very tight, therefore you have to grind the hub and the nacelle a little bit to be able to mount the ball bearing.

There are two versions of the base plate, one with a integrated business card holder (I have this model in my office), and one without. Both versions have a hub hight of 228 mm.
