Summary

To boost my radiator performance I've put fans on top of it. To make it look nice I wanted an easy way to create a snug fit between multiple fans. The screwless fan connector is born.

Tested with arctic fans but will probably work with loads of other fans.

Clipping on one side is enough for my use case but for extra sturdyness you can clip on both sides.

To remove the clip you need a wedge or long fingernails to get it out (it's snug!).

For maximum strength: Print with the flat side of the pins down! Else the pin will break.
 

Max overhang = 30%

You can try without a raft/brim but because the part is so small I had a 50/50 success so it's better to add it.
