the fixture is designed for some 12V LED bars from amazon. It's mounted on the printer via a T nut with a M5x8mm bolt in each of the brackets. The aluminum housing of the LED bar clips firmly into the brackets and can be adjusted in width. I designed it with a slight angle towards the printer, so you don't get blinded working in front of the light.
Many printers run on 12V already, so you can plug the light directly into the PSU or if your printer uses 24V you can use a buck converter like this in between.
