Prusa i3 MK3 Extruder Motor Cooler

thingiverse

Revised the original Extruder Stepper Cooler by CG-Tech, building upon modifications made by kvn5x4 to create this version. The modification by kvn5x4 encountered issues with Slic3r, resulting in holes appearing on the sides unless Detect Thin Walls was enabled. Enabling this feature led to odd artifacts in these areas. Made several adjustments to enhance the overall printed part. In place of a filet at the end of the bolt-on area, I added a chamfer to eliminate the need for supports and improve surface quality. One of the bolt holes failed to print a solid ring, instead leaving a gap. I corrected this issue as well. The bolt-on area has been thickened slightly to create a smaller gap between it and the extruder carriage when in place.
