Magnetic Stir Plate - PC Fan & PWM Speed Controller

This is a DIY Magnetic Stir Plate. I personally will use this for making yeast starters for home brewing beer. Others use them to make E Liquid for ecigs. The magnetic puck on the pc fan spins a magnetic stir bar which can be placed in any flat bottomed container. The stir bar spins, creating a vortex which mixes liquids extremely well.

Note: Be sure to orient the files correctly. I just exported them straight out of the SKP in the orientation they were in.
