Flexure Cat6* Cable Comb (4 to 20 cables)

These combs are designed to be zip-tied or hot-glued to wire shelf decking, I'm sure they will fit into other spaces as well. I'm hoping the flexure makes them work decently for cat5e as well.

Design considerations/quirks

The outer position in each slot is slightly smaller to account for splay and give better grip. The zip-tie holes are 3~mm x 4mm and arched around the would be center of the decking wire. The zip-tie holes are placed dynamically based on the number of slots, so the space between holes is not consistent. I do not expect you to use every zip-tie hole, two was enough for every position in my install, currently up to 2x8 size.

I originally printed this design in 4mm and that worked just fine if but it was going to be a challenge to mount them, I'm not confident the ziptie holes would have worked out, more for shape reasons than strength. Designed assuming a 0.4mm nozzle and 0.44mm perimeters, so the flexure is 2, and the bar between flexures is 6.

Applications & tailoring

The cutout along the spine is meant to sit on the wire of the decking, this relies on the lower wire being oriented perpendicular to the run. In the opposed case, you can still zip tie the comb to the perpendicular wire, but you have to be careful when you tighten them and it will never be stable in the same way. I recommend adding negative volume cylinders in your slicer, or adding cutouts to the fusion 360 model, but these will then lock the positioning of the comb so consider your needs carefully.

* I don't have much stock of cat5e anymore, but of the one I tested, it fit well. All of the cat7 I have is flat cable. I suspect the added thickness of round cat7 would begin to bow the combs, but you could probably scale it up a wee bit.

* Most of my stock of cat6 is two styles (see photos) so I don't have much variation, I can't guarantee this fits your cat6, but it's worked out for me so far
