*Update, I have printed the 21mm version... and it was scary strong using PETG.
Sometimes the simplest creations are the most useful. I was building a water-cooled PC and needed hose clamps, and was shocked to see average prices of around $10 for a pack of 10 and no designs online! This water clamp that I have designed will work from 10mm upwards, although the 10mm & 11mm clamps are pushing the limit of a 0.4 nozzle printing small teeth.
I have designed this piece to look attractive when placed on a water-block or in plain sight, therefore it is much more narrow than the nylon clamps you will buy in stores.
Careful considerations: Your choice of plastic is important if you will be using this on high heat applications, if you are planning to just sort wires then pla should be fine, but for watercooling or perhaps even car radiator hoses I recommend PETG or nylon.
For Watercooling using 3/8in. tubing use the 11mm size. (test pending)
For Watercooling using 7/16in. tubing use the 16mm size. (test pending)
*If using this on high heat or water sensitive applications, I can accept no responsibility for the structure of this creation... that will have to fall on you and the quality of your print/materials.
