120mm Fan mount for 2020 extrusions

Hi all,

just a small update with this 120mm fan mount.

I created this mount for my Two Trees Sapphire S, that I'm upgrading to have another printer for printing Fenrir parts.

I've upgraded the mainboard and added a BTTpi with Klipper, and the original 50mm fan for cooling the stepper drivers had bad bearings, and was noisy before they went bad as well, so a larger fan at lower RPM will be better both in air flow and noise levels.

This should be usable for other printers as well, so I thought it might be interesting for other projects. Hopefully you'll find a use for it. STL file is attached below. :)

Thanks,
Thomas
