Filament Cooling Dual-MK7

thingiverse

This mount and duct fits a 25x25x10mm fan and clips directly onto the MK7-dual-extruder-slide. You can clip one in the front and another in the back on the slide, providing a very compact filament cooling system that won't restrict the build volume. Depending on your fan's power, it might not be the most powerful cooling solution, but with one in the front and one in the back, it does a decent job. It can also accommodate four 3mm LEDs to illuminate the workspace. However, you should only install LEDs on the frontside piece. In the image, you see one installed on the frontside with four white LEDs and another in the back without any LEDs. There are two additional tiny holes around the rim of the fan to enhance airflow.
