Stepper cooling and chain mount for X-axis cable chain

thingiverse

My x-axis stepper motor is prone to overheating after a while, reaching temperatures of around 70 degrees Celsius, which is well above safe operating levels, making it inadvisable to touch for extended periods. I've decided to address this issue as well as another problem with loose stepper motor cables. Here's what you'll need: 1) An aluminium radiator measuring 43 x 40 x 11 mm - I sourced mine from an old, passively cooled GPU card, but feel free to modify the 3D model of the Stepper Bottom Alternative to accommodate a smaller radiator if necessary. 2) A fan with dimensions 40 x 40 x 10 mm, such as my Sunon 12V model. 3) Two M3 Allan screws measuring 25mm in length. 4) Two M3 washers. 5) Thermal Tape with a thickness of 0.5-1 mm to ensure good contact between the radiator and stepper motor.
