Wanhao Duplicator 4 (Makerbot) X axis stepper motor fan holder (with cable channel)
thingiverse
This part is just a small piece of a larger upgrade project I'm working on right now. I had some overtemperature problem with my stepper motors (shutdown during operation), so I decided to implement additional cooling for them. The part has a little shield to protect the workpiece from as much airflow as possible. The holder is made for 40x40 fans mounted with M3 screws. I have updated the part to v2. Now, it is possible to mount the part to the motor as well (no chance for falling down anymore), there is also a new cable channel connection point. Instructions The models are not adjusted for ABS printing. Scale XY planes by another 1% to adjust for shrinkage. Support and chain elements can be printed from PLA (less problems with warping, slower wear for chain).
