Nier Automata Black Box Container

Needed a prop Black Box for my cosplay. So I designed this on Tinkercad.
Turned out okay to say that I didn't know what I was doing.
I changed this one so we could take around a portable speaker inside. It's got a sliding lid. but it's a little tight so it might need some sanding down
