CLAMP'O'MATIC : Parametric cable clamp

I couldn't find a suitable cable clamp for my project, so I made one. Allows to attach a cable to a frame with 2 screws.

Fully parametric design, you can easily change the size of the clamp, the diameter of the cable and of the screws.

There are two clamp types :
1) Half-clamp (blue) : two clamps can be attached together to prevent the cable from going through a hole.
2) Full-clamp (yellow) : a single clamp can be used, screwed to a flat surface, to hold a cable.

Both types can be generated from the same OpenSCAD file.

This is my first published design, comments welcome.
