This is my version of the ultimate cable management system.
It comes in five different predefined sizes, with maximum internal cable heights of 8, 10, 12, 15, and 25 mm, so there should be something for everyone.
The straight sections are available in predefined lengths of 50, 75, 100, 150, 200, and 250 mm, but if you need a specific length, you can easily customize it yourself in the customizable file.
 

If you want to customize the other parts in the future, I can try to upload them as a parametric version.
 

The parts can be easily connected to each other using the connectors, which hold them together and ensure they are perfectly aligned. The straight sections also have a recess for a cable tie if you want to strap your cables to the base.
 

So, have fun declaring war on cable chaos and transforming it into an orderly, attractive design—the only limits are your dreams. Have fun :)
