Ratcheting Hose Clamp

I've always thought these clamps are cool for some reason, and I'm also working on a customizable version.

The design is a little tricky though since the circles are all
"unwrapped" when in the neutral position.

Anyway, have fun with my scan if you want. Works with about 3/4 to 5/8 tubing. Or you could also try scaling it and see what happens.
