OSH Park cost and turn around are so great, I find myself skipping protoboards most of the time. More fun to spend an evening designing a custom board than bending a bunch of error prone wiring.
I too have used Eagle and OSH Park for custom hardware! Mind you, none of mine ever turned into full fledged consumer products available for the masses.
As someone who likes to dabble in electronics, and a custom PCB here and there - let me just say, in proper Wayne’s World style, I’m not worthy. Unreal. Gorgeous. Amazing. Top notch.

I love this stuff! Definitely started with messing around with Arduino. Have since gotten into designing my own PCBs and sourcing parts on DigiKey. I’m no expert, but it’s more approachable than it seems.
If the jack can’t be tightened, then you have options, and the right one is kinda up to you. If you can find one with a similar size/footprint, you can de-solder and replace. Worst case, I can make you a new PCB, or you can dive in and learn Eagle!

I did something similar a while back, but 3D printed so I could attach to a baseball cap. I used an nRF52 so I could control the sequences from my phone.
