Last weekend I found an hour or two to relayout the PCBs to fit into the square tubing better. The boards are thinner and theres a tab below the microcontroller so you can grab it with a pair of pliers without damage.

There’s also a white silkscreen square to write an address to identify each PCB (since they’re addressable)

Then I checked the gerbers with GC Prevue and sent them off to 4PCB.com tuesday afternoon. With 2 day turn and overnight shipping that means they arrive Friday. Since it’s Kate’s first order with them, she gets $500 off the order… Basically we pay for shipping ($50).
Tomorrow I have to solder up 80 Duel Nature PCBs (maybe try out making silkscreens on the lasercutter)
