UPDATE: Wasn't totally happy with some of the teeth. Went through the process again to clean up some of the teeth and simplify the mesh further. Most recent is clamp_remix2.stl

Remix just to clean up and simplify the mesh a bit. Starting with SVG file, workflow was: GIMP, Inkscape, Blender. Set the z-depth to 5 mm (as opposed to ~6.4 mm in the original).

This will fit 3/4" OD tubing. If you are using it to secure a hose barb it may need to be scaled up (~105%) to fit around and clamp well. It is quite secure, but I wouldn't recommend for critical applications.
