space invader hook

A simple clothes hook that looks like a space invader. There are different space invader available even the space ship :). I optimised it for open it in the customiser app. I will add more space invader once in a while.

For the latest Openscad source file, have a look at my github repository here: https://github.com/schub/basteln/blob/master/space%20invader%20hook/hook_generator.scad
