I will need to print or use a pcb for a backplane to give some structural integrity (I didn't correctly size the corners near the keyed assembly pieces or design slotted pins like on paper dolls), but the parts are coming together nicely.

I'm using a failed (delaminated) print to keep the sides straight while the glue sets.

Actually a pcb backplane would work nicely since I want to put power distribution on this. I sure wish those usb ethernet dongles had worked, because I found a 5 port switch at the goodwill going for $3. Best part is, it matches the footprint of this box almost perfectly!

Without the caps, you can fit 8 Ok Zeros in here, however, I found that after plugging a OTG adapter AND wifi dongle, it can get a bit tight. Might need to widen the leaves or make an adapter. Right now, 4 bramble leaves is optimal here. And, if you think about it, you have 4 cores, and 2 GB memory total. $20 to simulate a Model 2B for compute power? Not too shabby.
