With a big enough 3D printer and ample filament (I think it used about ¾ of a roll), printing the console should be fairly straight-forward and easy; changing filament color mid-print for the panels and lights is the most complicated part. Everything can be found on Thingiverse here.

Using the PCB I made (or something similar) is definitely going to save you some time wiring things up, but there are obviously other ways to get all the switches and LEDs wired up to a microcontroller of your choice. While I created a schematic for the PCB, I didn’t create any kind of guide for the wiring of the switches. If you’re getting stuck, let me know and I can throw something together.

Assembly will ideally be pretty quick and easy. One hiccup I ran into (my own fault), is I failed to make sure there was enough clearance below the Abort and Landing switches. Ultimately, I had to grind a bit off of them in order for it all to fit. If I were making another, I’d make the console a little deeper to avoid needing to do that.

The code is located on Github here. It’s written for a Particle Photon but should be easily edited to work on a similar Arduino.
