This is a set of clips to mount a couple of CCFL Tubes (like these: http://www.directron.com/ccfl303uv.html) to the back of a MakerBot Cupcake CNC. Now I wish I had some plastic that looks better under a black light...
Download the file.
Print the set.
Clean them up to your liking.
Clip them to your CCFL bulbs.
Slide them so that they hold on to the rear window of your MakerBot.
