Case
All print files (STL, STEP, X_T) can be found in assets/case. Alternatively you can view the project on OnShape where you can export the files in a format you like.
Wiring
You have to short-circuit R0 on the RS485 boards to enable the termination resistor required for DMX before the first and after the last device in line.
