Only print this if you're sure what you're doing!

This, uh, has some problems; might be non-manifold, might need some cleanup in meshmixer or whatever. More an exercise to have an excuse to fiddle with OpenScad.

On my machine (Cura 4.11) it did seem to slice mostly correctly (a few extra perimeters in the middle of the print). Try it out if you want, just keep an eye out for potential issues
