The parts that I got on order last Friday have started showing up. I'm still waiting on the PCBs, but I'm not expecting them until early next week. Yesterday at lunch I used the PCB mill at work to cut out 4 copies of the interface PCB. That way I can test it out, and if my boards from OSHpark don't show up in time I have them as a backup. I've also been working on redesigning the center 3D printed piece of SAB3T to incorporate the board mount and the 1" ball bearing holder. The main reason that the board mount was separate was so that I could stuff all the wires underneath. There are a lot less wires now with the PCB, so it was sub-optimal to keep the same setup. As I type this I have what I think will be the final version of that mount printing.

It looks like this weekend is shaping up to be a busy one, so hopefully I can keep to my schedule!
