Sure, patch cables are rarely the exact right length, but you can get pretty close I also organized the rack so that I could use mostly a single length of patch cable (6"), and as a bonus the switches get some room to breathe. I generally try to keep dozens of patch cables in varying lengths on hand in general, though for a project like this, my design let me put in a bulk order for ~120 6" cables.

I never make my own anymore. At least not in this quantity. It's not worth my time, TBH. And I can pass the cost along to the client anyway
