Extruder fan (50mm) for Printrbot Simple Metal

thingiverse

This is a minimalist mount specifically designed for low-profile 50mm fans on Printrbot Simple Metal 2014 to keep extruder motor temperatures under control. Screw holes are carefully crafted to accommodate countersunk self-tapping screws - the type that typically comes with PC fans. A standard-sized 50mm fan fits snugly in place without any issues. For those looking for affordable alternatives, a good option is to repurpose hard drive coolers, which often come with two 50mm fans and can be had at a lower cost than buying separate units. In order to make room for the fan, some minor adjustments are necessary - it was discovered that the bed sensor needed to be repositioned. An alternative approach would be to simply flip the plate over and install the fan on the outside. A complementary Sketchup file has been included to simplify resizing of screw holes and any other modifications you may require.
