This is a remix of the "Cable Clip for 50mm truss" from Florian. I've removed the extraneous contoured tips from the original and created a new version that turns one of the extraneous contoured tips into an additional clip to manage a single cable. I have also added a “narrow” version of both of these models in addition to the original width (the stl files labeled “wide”).

The “wide” version of the clips is 20mm and the “narrow” version is 10mm cutting your material considerably. 

In my testing the “wide” version grips the truss really well and is great for “heavier” cables while the “narrow” version has less grip on the truss but is a great option for a small number of data cables, especially if you're using multiple clips along the truss to prevent sagging.

I suggest printing these with PETG for the flexibility and strength needed. I've used the following print settings with success:
- .2 layer height
- 4 walls
- 20% Cubic infill
- 3 top and 3 bottom layers
