Stackable Arduino UNO Gridfinity 2x2x3U

I liked the original gridfinity implementation of this for an arduino Uno - But was surprised this was a flat print, so was not stackable - so I combined this with a standard 2x2 3U bin so it now stacks. Its nice as the original fitted Uno's with USB A and C - and now you can stack them and use the original model as a ‘lid’
