Summary

Great case! thanks https://www.thingiverse.com/0110-M-P for the original design. This has been my go too case for the raspberry pi. I recently converted my 3d printer to klipper and came across the BIGTREETECH BTT Pi V1.2.1 and needed a case. After trawling through the remixes i didn't find one so thought I would create a remix using FreeCAD. It is very similar to a Raspberry Pi 3 however it is mirrored and has slightly different IO placement. I include the STLs and STEP files.

Files:
Top: This is a blank top incase anyone wanted to remix and add their own ventilation design.

Bottom: This is the bottom part required for this case.

Bigtreetech: This has the BTT logo for ventilation

Klipper: Has the klipper logo as the ventilation slot

Vent: has a more conventional vent slot

Any questions or advice are more than welcome.
