Ultimaker X Stepper Fan

thingiverse

This is a fan holder for a 50mm x 50mm x 11mm fan. It was inspired by this thing: http://www.thingiverse.com/thing:8183 I made it because I could not find the right current setting for my stepper driver to keep the motors cool, and not lose steps. I've added a butchered heatsink to improve the cooling capacity. Now my X stepper stays cool, and doesn't mis a step! As an added bonus, there's a hole for the wires. The Y heatsink doesn't need a fan because it's bigger. It's held in place by a suitably edited large paperclip. Instructions Find right fan / hack scad file to adjust for your fan. Print holder Mount heatsink to stepper (I've added some Artic Silver thermal compound from my overclocking days between the motor and the heatsink for even better cooling performance. It's held in place by tie-wraps and paperclips until it falls off ;-) ) Clip holder on ultimaker Connect fan to power print more and faster with cooler motors!
