i 3d printed something to cover my car's radio display. it only functions as an aux input to my phone anyway, literally the only thing it does is output audio and have a volume knob. there's no need to have it lit up in my car interior destroying my night vision with its tacky fake VFD-style panel backlit with 2005-cool-tier blue LEDs.

...that was my rationale I came up with for why I made and installed it, which I would give other people who asked. in actuality, it's because I can't see the volume number anymore. what I don't know won't hurt me. I'm free.
