Bidet file

We never actually ran out of toilet paper but the threat of that happening made me 3d model a thing that can be attached to a plastic bottle and work as an improvised and mobile bidet. I tried it, it feel refreshing, and although I prefer toilet paper it possibly is a camping option.
Here is it on Thingiverse and here on GitHub.

Needing a thread in OpenSCAD for the first time, I also wrote a thread module, which works with rotated and translated hulls around the thread profile.
