BTT CB2 simple cooling fan mount

Needed a fan mount my for my CB2 with an aluminium heatsink applied to the CPU so I made one. It's a simple design that allows you to to use aluminium heatsinks up to about 5-6mm tall. I've made 2 models- one with 6mm hexagon holes to fit wider screws and one with 5.8mm holes for smaller ones or if you want to press fit them.

You'll need these to attach the fan and the mount:

-M3 nuts x4

-M2.5x8 screws x4

-M3x16 screws x4 (depends on the fan, I used M3x16 flat head screws because the holes were too tight to fit any normal head screw), M3x20 should theoretically fit if there aren't any heatsinks below the screws.

Should theoretically work with any raspberry pi CM model and BTT CB1 because they all use the same mounting holes

In case anyone needs to mod the file I also added the source file made in Inventor 2022
