4040 Profile Trunk Cable Management

I've now improved on this design along with my other 4040 profile clip to create this:

Improved Modular 4040 Profile Cable Clip by Googlebug - MakerWorld
 

Very simple, reusable trunk cable management for 4040 aluminum profile typically used for industrial racking, or in my use case a sim rig.

The bottom clip slots into the grooves of the profile, you then rotate it by 90 degrees. It will be a tight fit so that it doesn't move especially when added onto uprights.

This is not intended for individual cables, it's for large volumes of cables wrapped up in their own trunk / cable management as shown in the photos.
