Parametric Cable Holder for Strut Channel

This is to mount a bundle of cables on Strut Channel.  

You can mount with ¼" bolts and standard ¼" strut channel nuts, or go DIY a bit more and use my 3d printed ¼" strut channel nuts:

I have a bunch of model sizes to print directly but you can also customize with the included Fusion 360 file:

My use case:  I'm building a home server rack and I added strut channels to the back of a 2 post wall mounted rack to help manage cabling.  A 4 post rack would have been an option, but I was already committed to a 2 post.  Strut is a complete overkill, but you can buy 10' lengths for $25 and the modularity of it is amazing.  The cost of bits to bolt everything together adds up quick though.  I used commercial nuts for the structure, and my DIY nuts to mount the cable holders.

Printing tips:

• Print on the side
• 3 walls
