A cheap solution to your "under the desk cable cluttering" issues. Just mount a DIN rail to the bottom of your desk and arrange these mounts on it to hold your cables neatly.
The ratchet and its lever is a single object. You can print the entire thing with or without support.
I could not find any nice and cheap cable management solution which would be highly customizeable and would cover all of my needs - that's why I have designed the DIN rail ratchet as well as the other simplier models. Perforated DIN rails are cheap, available worldwide and all you need is some glue or a pair of screws to attach them anywhere.
