Under-Desk Heat Shrink Tubing Holder 3 Sizes

I have a workbench with three boxes of heat shrink tubing stored underneath that I use frequently. Constantly bending down and taking out the tubing directly from the boxes was getting very impractical.

My solution was to design this under-desk holder that accommodates three different tubing sizes (in my case, L: 6.4 mm, M: 4.8 mm, and S: 2.4 mm). The bracket mounts under the workbench at an angle, leaving the ends of the tubing exposed. This allows me to simply pull out the required length and cut it on the spot — much faster and far more practical than before!

Print & Assembly Tips:

Storage / Setup: I recommend securing the three tubing boxes in place so they don't slide around when pulling the tubing out.Material: PETG or ABS.Supports: No.Scaling: If you use the same tubing sizes, no scaling is needed. If you have different diameter tubing, I recommend modifying the hole diameters in your 3D CAD software to fit your specific needs.Mounting / Fastening: I mounted mine permanently using 2 generic wood screws and 2 nuts. I've been using this setup daily for over a year with zero issues!Measurments: 50mm x 43mm x 17,5mm.
