UPDATE: Added the "beef" version. This is just a thicker, more durable version with a slight tweak at the end of the clip so you don't bleed like me when clipping it closed and accidentally catching your finger. I also removed a little material from the clip because I suspect if I didn't, it would never bend enough to close it. I made a thicker version to reduce deformation from pressure from the cables while closed and to reduce the chance of the top bending horizontally.

Update 2: Added Beef V4. Makes some shape adjustments but also adds a tab to the locking part to making closing it easier. This also uses less filament because of the holes than other versions.

The base for this was taken from https://www.thingiverse.com/thing:330151 "Bag Clip - PLA compatible" by MasterFX. If you want the base of the clip, go there.

There are 3 versions I uploaded. A very basic, no mounting 85mm length and 2 mountable 65mm length.

The hole sized are roughly 5mm, 4.5mm and 3mm. The holes are specifically sized for my needs but in my case the 5mm snugly fits a Cat6 patch cable, 4.5mm fits a thin HDMI cable and the 3mm fits a small audio cable. Aside from the clip itself, all the edits were made in TinkerCad so its fairly simple. The V4 would use about 11g of filament on normal settings according to Cura. No adhesion or supports. I printed this using the Dremel slicer on high speed, 0.34mm and it printed just fine. The hinge pin needs to be worked just a little bit by opening and closing it a few times.

On testing this, I screwed it to a wood desk and gave it some decent "accidental" tugs and it held just fine. A little cable slip on harder tugs but thats good. Its reducing the strain on the wires. Tugging harder than you ever really should, the top opened. That's the "point of failure" if you really go too hard pulling. I have yet to test the beef version.
