120mm fan holder for 30x30 aluminum extrusion

This was made to attach a 120mm fan to a Hypercube evolution. I think with this even the hotend heatsink fan could be removed if you use a bed sticker and print only in PLA.

There are two versions, one for use with the self-tapping screws that come with the coolers (through holes.stl) and one for long M4 bolts and nuts.

Can also be CNC-milled.
