MK3s+ extruder motor and gear cooler
prusaprinters
<p>I made a remix of a extruder motor cooler. This is for the new MK3s+ that has some airflow over the Bondtech gears.</p> <p>This one uses both openings on the left side of the extruder but doesn't block the tension screw for the Bondtech gears.</p> <p>I haven't tested it yet. But with the parts that I have printed I have checked that there is enough room to move freely.</p> <h3>Print instructions</h3><p>I printed this in PETG. PLA is to brittle to bend and install.</p> <p>0.2mm layer height and 15-20% infill.</p> <p>There is no need for supports. I added a little support in the print to support the part that fits next to the Bondtech tension screw.<br/> That support is easy to cut off.</p>
