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. The ratchet and the lever is a single object. You can print the entire thing with or without support.
