Ender 3 Micro Swiss Direct Drive Hot End Fan
thingiverse
Designed for dual 4020 fan and BL Touch. Decided to make a cooler that fits directly to the Micro Swiss DD bracket as I wasn't happy with the other designs I found. Bigger cooling nozzles in prototypes allow for the part cooling to flow and not have as much static pressure. Didn't do any motion analysis but results tell me it works. I made it so both pieces would be easy to print with the front side down. Prints hollow with support only on the bed using .4mm nozzle and .16 layer height. Utilized some M3 screws to secure everything. Depending on wire output side, mirror the fan mount. The narrow part of the fan mount goes on the top. Printed in PETG but don't see why it wouldn't work with others.
