Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2916303.

Followed the advice from this thing for a PWM fan speed controller and mount.

I purchased a different PWM controller and have a different printer, so I designed this for its power switch and potentiometer. I wired it to the stock blower fan, but you could also add a separate fan if you wanted. It comes with a three-way switch, but I only needed on/off.

This fits on the right side of the printer below the SD card/USB port and uses an existing screw to keep it in place. The switch was a tight fit, and I had to use a vise to press fit it.

I mounted the controller board to the bottom alongside the other components with a simple bracket (that also holds an upgraded Trigorilla MOSFET based on this thing).
