I didn't go with the cable channels, I instead used cable tie bars, and also some cable clips I had 3D printed a year or more ago but never gotten around to using (there's a black one to the lower left of the power strip).
It's not as clean as Katie's because of the lack of channels, but it I'm happy with it, it keeps the cables up from getting caught in my feet and from normal height it is all clean.
I kept having problems with my docking station falling off (lower right "Dell"), but it was also hard to get at some of the ports because they were close to the cross bar of the desk. I stuck a couple of the underwear adapters on the docking station, so now I can easily pull it off to get access to those ports, then just click it back on.
I also printed a bunch of 3x3 grid in PETG, and mounted it to a couple 4x4 posts I have with hose reels on them. Then I made some hangers that I can put my hose tools on, and I finally am keeping them out of the dirt.
She just posted some photos of installing some of the grid on the cabinets under the kitchen sink, which got me to thinking I might want to do some organizing there. Katie seems to have the grid installed all over.
I'm quite happy with my value-cable-holder, everything fits in and it only needs two screws to attach: https://www.galaxus.ch/de/s4/product/value-kabelfuehrungssys...
Looks like a pretty good system though!
This is slightly better because the design seems to be simpler and easier to print.
But I would rather have something that I can buy and also extend.
