thingiverse

Cooling fan shroud/mount for MY1020 motors. Motors vary in length, the tabs accommodate 136mm long motor. If your motor is smaller than 136mm no problem, if your motor is larger than you will have to sand off one of the tabs. Shroud mounts to motor using cable ties. Fan is 120x120x(25) mounting holes center to center is 105mm I used https://www.amazon.com/gp/product/B07TV2WKRD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 amazon doesn't show but it comes with a fan shroud. Note the fan is 48 volt, choose a fan with your voltage in mind. My motor is 1800 watt and before the fan shroud would get uncomfortably hot, with the fan it barely gets warm even propelling my recliner at 19mph in hot 4th of July parade for 30 minutes. Very effective. fan/finger guard attaches with 4mm screws and nuts. There are pocket in the shroud to capture the nuts. I used 35mm long bolts to attach fan and shroud. There is a switch pocket designed in for a "KCD3" switch and provides room for wiring inside. https://www.amazon.com/gp/product/B07N82DJZF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Part was printed fan mount surface down with no support needed. Prusa Mk3s printer. I used PLA. Enjoy!
