I had some heat issues with my (PLA) extruder and X-carriage, a M3 threaded rod melted through which I used to mount my hotend. I decided I needed some active cooling before I printed a new X-carriage and Extruder in ABS.

So I designed a simple mounting plate for a 4cm fan which bolts on to the bottom of the X-belt clamps.
