Instructions will be detailed when I have more time, but this is essentially my first original build; a raspberry pi box like so many others. This one I designed to also fit a USB hat I had bought many years ago and didnt like leaving unprotected as the original hat only came with acrylic spacers and a partial coverage top and bottom.
This is meant to use 4x M2.5 bolts and nuts.
Nuts can be press fit in the bottom of the case, while the bolts go through the pi, spacers, USB hat and bottom of the case. Bolts should not interfere with the lid.
Current version does not have sufficient room for standard soldered headers on the Pi
