MKS Gen L stepper driver 40mm fan duct, JGAurora A5X

thingiverse

This fan duct fits perfectly on the MKS Gen L and is able to use a 40mm standard fan. I designed it for the main box of the JGaurora A5X, therefore I tried to keep everything in a low profile. It has the needed cutouts for some board connectors and fits on the standard board mounting spots. The height of the air channel is 38mm, and I have no issue by using TMC2208 with large coolers. My prior design https://www.thingiverse.com/thing:3636965 was good for a standard use, but with the TMC2208, higher stepper voltage/current and fast extruder speeds, I suffered some extruder skipping on larger prints due to temperature issues. This issue is fixed now. Good thing, no support is needed. You can print it with the mount for the fan on the print bed. If you like my design, feel free to offer me a paypal tip ;-)
