NEMA 17 Heat Sink and Fan Mount

Original design by zuberio.

The design makes use of a 40mm fan and a heat sink with dimensions of 40x40x11.3mm. Just like the original, make use of M3 screws to mount the fan in place. The mount can be used on the motors on the x,and extruder. If mount is loose, having a heat sink adhesive can help keep it on the motor.

When printing, the infill may be as low as 20% but it makes it weak. Higher infill may be desirable because of the design. Aside from that, if your motor can reach high temperatures, I would suggest a more temperature resistant filament like ABS or PETG. Lastly, please be careful when removing it from the print bed, you may end up breaking the legs of the mount.
