ZeroBlox - Lego compatible Raspberry PiZero case

I've always liked the Pi Blox case for the Raspberry Pi but couldn't find a similar one for the Pi Zero so thought I'd make one.

Based on excellent original block code by JAG (Jeremy Green) on Thingiverse.

I've made quite a few tweaks to get this to print successfully. The top was fairly straightforward, the bottom however took a lot of work to get the pins and walls to the right dimensions so it would connect solidly and securely every time.
