The first thing I uploaded to Shapeways. It's quite a fun little shape to fiddle with or to put on a shelf. Original description as follows:
A sort of wiggly shape, made using TopMod3D. It was originally going to be hollow, but the Rind Modelling tool produced unprintably thin walls. And this version (luckily!) isn't as large as the eight-metre previous version.
(incidentally, 'infinitangle' is a portmanteau of 'infinity' and 'tangle'; obviously, none of the angles in the shape are infinite!)
