So I had three options:
- Get a 0.6mm FR4 PCB, bend it and hope for the best. Probably won't end well.
- Get a flex PCB. Probably too unstable for the big parts and connectors.
- Make a semiflex board myself by keeping some strips free of copper and parts on the top layer, then milling them down.
I decided to test the third option with some scrap boards and, apart from me not really having any experience with milling, I think that's a viable solution!

@cato@chaosfurs.social looks like you've got a solution already; as a fall back, consider dead bug-style with the parts glued/siliconed onto a curved surface

PCB design done! This will do: - Eye light - Horn lights left and right - Fans - Spare output - Inputs for 2 side buttons for control/navigation - 1 tongue activated button to control basic things hands free - 1 boop sensor input - Display for inside the head to show me what I'm doing with e.g. the tongue button - amplifier for speaker to play sounds e.g. when booped OR to use as a crappy bluetooth speaker as a gag since the controller has Bluetooth - SD card for storing sound files
