Summary

Edit 9-25-2021:

Didn't fit quite as well in real life as cad, so adjusted/corrected some things.

When I went to put the first one together I discovered that I didn't have any screws that small in diameter with that length. So, made a version that uses small cable ties to hold the lid on.

Another Rock64 case

Recreated the model in CAD

Found a model of the board, altered the box a little for better fitment and added some mounting ears
