120mm fan cover grill (Patreon)

Make sure you have a good clean surface and perfect mesh before printing, as the first layer is intricate.

6mm thick, with 4mm clearance between fan and grill.
Use regular self tapping screws like used on computers.

I use this on my printer PSU, and now my fingers don't get sliced!

I use the Arctic 120mm silent model for the ender PSU, as even at full speed it's super quiet and offers plenty of cooling for the PSU (Amazon)
