CWWK Mini N-Series Heatsink M3 LNut

I didn't have the right length M2.5 screws, my M2.5 threaded inserts were press fit and I didn't want to wait for more hardware to come in, so I adapted the L nuts to what I had on hand.

You will need:

• 4 x “M3nS” - M3 DIN 562 square nuts commonly used in 3D printer builds.
• 4 x M3-0.5x16mm screws.

Just print the part (I used 0.2mm 15% infill, no supports, square slot vertical with the wide end on the bottom), slide the square nut in, attach to the fan mount plate, slide it onto your router, and tighten.

Adapted the “fan support hooks” for M3 screws & M3nS square nuts.
