OK, here is a model I have created in Sketch-up. The inspiration
was given to me by my buddy when we were talking about Cable Management. He submitted his own version (https://www.instructables.com/id/Cable-Carrier/), while I took my own path. I have included a swinging lid to easily install and remove your cables. Along with a customizable dividers, to keep your cables in order as you wish. This is more of a quick model for you to download and print, rather than a walk-thru of how I created it.
I have included each part in .STL format (each model was check and found no errors for 3D Printing), along with the full group of parts to be printed in one .STL file. Made the plug fit snug in the parts, may have to use glue to hold it in, I don't know. I have also added the Sketup file, for anyone that wants to download it and easily modify the design to their liking. Below are pictures of the model, along with render images of it in Maya, and an animated video in Maya on how you would put it together.
If anyone gets time to print it out, please let me know. I would love to see what it actually looks like, as I don't have a 3D printer.
