Here is my complete UFC. The wiring looks a bit of a mess, but every button, switch, and knob works! I am using a Bodnar BBI-64.
The main body and knobs were printed on my Ender 3, the front panels were laser engraved and then machined on my CNC router. I laser engraved button labels as well, but didn't like how it looked with the extra thickness stuck onto the buttons. For now, I just made some stickers on my inkject printer. Looks ok although the black doesn't quite match the laser engraved panels. Good enough for now, I may try to come up with a better solution at some point. I fly in VR so it's really not important, but I'm a bit picky about stuff like that so I'd still like to make it better.
Black acrylic blank out panels for the LCDs for now. I would like to make those functional but need to do a bit more research into DCS BIOS and find LCDs that fit well.
The angle and "stick-out" relative to my MFDs isn't to actual hornet dimensions, I had to have the UFC stick out a bit more to make room for some of the toggle switches inside the box.
