Didn't have and couldn't find the aluminum channel for the LED strip lights, so I printed one out of PETG. So far it's holding up. I don't keep it on all the time, and I haven't don't any really long prints yet. Please use at your own risk and keep in mind that the lights can get warm, so I definitely wouldn't recommend using PLA.

Print instructions

I'm able to print this all in one piece diagonally on the print bed. It's a very tight fit so the tool path may have to be cut away. Definitely no room for supports or rafts.

I used white for the lens, but you could use clear or natural as well. Good luck!
