Compression Clamp Assortment

I wanted to make a clamp for my Air Compressor to hang my air nozzle from and i wasnt sure exactly what i wanted to use so i decided to make a handful of different choices.\

Standard - Used for the backing unless you want clamps on both sides
Vertical Ring/Loop - Ring runs parallel to the pipe/tube
Horizontal Ring/Loop - Rung runs perpendicular to pipe/tube
Quick Release - Blank, like the standard but has a "Tray" to fit my quick release handles in
Hook - just a short hook with angled tip.

I decided to make all 5 variants in a 25mm tube size and then a 30mm tube size, These are both built to use M4 sized screws and nuts.

I did figure out a couple of other sizes you can easily scale to:
* If you start with the 25mm pieces, and scale them down to 80%, they can clamp on a 20mm tube and use standad M3 screws and nuts.
* If you start with the 30mm pieces and scale it up to 125%, they can clamp on a 37mm tube that use the standard M5 Scew/Nuts. Of course you can figure out
