So I found this LED goose neck style adjustable clamp lights on amazon and wanted to use them for lighting the printer. I wanted to be able to control the lighting better to highlight the build plate and printer depending on the materials I was using. So since Prusa have put this useful hold at the top though I would use them. The clamp LED lights where held to the clamps with standard screws / bolt. Measured and quickly through this together. Hopefully it give people some ideas for different lighting options.
You can use any material. I had some Silver Prusament on the printer at the time. But PET would be a better choice for strength.
