The model is made for the Raspberry Pi 3 as those are the ones I have, it should work with the other models but I haven't been able to test that yet. If you have other models and it works for those please let me know. It is designed to fit on a 3x2 Gridfinity base.

-EDIT: I made a mistake in my first upload and labelled this as a model for a Pi 4. This was an error and Was meant to be the Pi 3. I have updated this, and apologies to those who downloaded this thinking it was for the Pi 4.
