Stirplate PWM Controlled

Stir Plate for homebrew yeast starters. My other thing, http://www.thingiverse.com/thing:198838, used a 12V fan I couldn't get to go slow enough, even with a PWM Controller.

So I made on to work a typical motor. You can modify the dxf to work with whatever size motor you have. My motor was 1.4" in diameter, and slightly over 3 inches long.

It has a mount for the PWM Controller: http://www.amazon.com/gp/product/B009HKFAIQ/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1
