Fluorescent Tube Holder - Designed to hold the UV tubes in my PCB exposure box. The ABS has enough spring in it to clip onto the tube. A bit scary at first but it works well. Printed on an UP! Plus using 0.25mm layer thickness and loose fill.


  1. Print flat side down.
  2. Insert M4 nut into holes.
  3. Mount to surface using M4x12mm Machine Screws

I'm curious why you don't just hold it with the tube sockets? While this might be OK for an exposure box, tubes can get pretty warm if they're ON for awhile. Just something to be aware of.

These tubes don't get overly hot being only 15W so its not too bad, but yes it could be a concern. The way I have designed the box didn't allow for the traditional tube holders. I am using screw terminal type connectors on the ends.

Really nice design! But would also agree with the previous poster. I'm about to build a UV exposure box myself and I will just use the tube sockets. Allthough, these would be nice to use for somewhere else and in like.. well.. "techno"-style designs, where you just connect wires to the end of the tubes. I don't know, but I can see the use for these! :)

Do you have any link to any projectpage or gallery regarding your UV-box? I'm searching for ideas from more or less every UV-box project out there ;)
