Transparent isolation washers?

I know nobody manufactures them, but with 3D printing so prevalent, I'm sure somebody could make them.

The most practical use for these would be to add LED lighting to vintage pedals without having to drill or modify in any way. The washers could either be for a 1/4" jack or the stomp switch. With how ridiculously bright LEDs are these days, I'm sure the light would bleed out just fine.

I can't have any see through washers Lars as how am I going to hide my drilling, paint and epoxy scratch off mistakes

Laser cut acrylic may be the way to go.

Yeah, laser cut acrylic would probably look clearer than 3D printed as long as you just want simple flat geometry.
