UP! Mini Extruder/Stepper Motor Extra Fan Mount

thingiverse

UPDATE: Some modifications to this part: extra magnet mount in the bottom mounting holes for the Octave Temperature Control/Switch. The Nema 14 in the extruder head of the Up! Mini gets a little too hot with bigger projects. This mod adds a high efficiency fan to the motor to have it running cooler. I repurposed a fan from some broken electronics I had lying around. The casing/duct holds securely to the stepper motor with 4 small neodymium magnets (6mm/0.2" diameter) and it can be completely removed by simply disconnecting it from the JST connector. The design adds very little weight to the extruder and works flawlessly. Instructions I printed it in .25, normal speed, 10% infill, 3 layers. Raft and minimal support (settings may vary from printer to printer). To secure it to the stepper motor there are mounts for four small 6mm (0.2") diameter neodymium magnets. Just glue the magnets in place and you are good to go. For the bottom magnet mount you just have to slide it into place and it should require no gluing.
