Cat fence 1

This is a little "fence" that clips to a bar on a garden door. It sits in the gap between the door and the mosquito screen, that would be just big enough to allow a cat to sneak out (or in!)

One or two of these should prevent that.

The cat in question really likes to stare intensely at things, so i thought it'd be a nice opportunity to have some 2d/3d fun, although the design could have been anything (or just a flat screen). (There's an example with text commented out in the scad file).

The project is done, and i suppose the code is what it is (a mess ;-> ), but since it's all pretty parametric, i thought i'd share it anyway in case somebody likes to recycle some of the code or anything.
