Made my gf a keyboard for her birthday and she’s enjoying it, but is missing light up indicator when caps lock is on. I know this key sucks and I disabled it on mine but she uses it a lot for her job.

The keyset I got her is completely opaque so you can’t really see the caps light unless you’re right above the keyboard looking at the edges of the caps key.

I took some spare keys of the same shape and drilled holes right above the indicator light and it shines through pretty well, but want to fill it with something clear to make it look nicer/diffract the light a bit. Does anyone have any recommendations? Was thinking about using polyurethane caused I’ve used it for random other things and seems like it could work.

Thanks!
