Orange Pi Zero with Expansion Enclosure, Slightly Enhanced

I liked the original design mostly but I wanted M3 socket head cap screws to be fully recessed in the bottom. I mean I have button head screws somewhere too but, eh.

And I wanted the lid to actually hold the antenna up.

And then I thought it was weird that there was a 2mm gap by the expansion USB ports.

Plus I made a version with two extra holes - one for a 5.5x2.5mm dc barrel jack (to power the board via header) and one for a 3.5mm 3 pole jack to use for a serial console cable. Beca
