Z Stepper Fan Housing for Dual Belt Z Ender 3/pro

thingiverse

I recently Upgraded 2 of my Ender 3 Pro's to Belt Driven using Kevinakasam's https://www.thingiverse.com/thing:4243512 His design is amazing! However, Since upgrading my Enders to 4.2.7 mainboards, ALL of my steppers overheat during normal printing( Even after altering Vref's on both boards, and I can't find a way to fix it ). So I designed this fan housing to slip onto the Z Stepper Motor and clip right onto the ledge of the Transmission_Rotated_Bearing file. This will actually fit perfectly onto either version of the Transmission. I have tested it on both. The only hardware needed is 1x to 4x m4 or m5 bolts to attach the 4010 fan to the housing. I'm new to designing 3d objects so please show me your makes and remixes! I Would love to see what you guys would change!!! I Print with a 0.5 nozzle and either 0.36 or 0.4 layer height 20% infill Supports - All Over 10% support structure Lines support infill 60mm/s print speed with 1000% acceleration settings on all options Takes 1 hour 13 Minutes for me to print this part. You may have to shave a little off the side depending on where your Stepper is spaced by the Transmission body. To Install Remove the Support structure from the print. Unplug the Z cables from the Stepper. ( this only works if you turn the motor so the wire harness is facing down ). Place the Wire harness hole over the Harness part first, then slide the top over the Transmission body and let it clip onto the side of the Transmission. Presto done. Thanks everyone for checking my build out! Edit 4/25/22: forgot to mention, I have no idea if this works on any other brand of stepper. I sized it for my Stock Ender 3 Pro Z stepper.
