Looking for TC items for a pet named Euler. XD

What I've found so far is the ice figurines, a couple of gems, some dice, the math textbooks, and, of course, the wonderful Geometric Fruit. But are there any other polyhedra or math-related items out there?

It's a bit of a stretch, but has a compass on it.

Hmm... that's not bad. It has a grid on it, and most math is usually applied to something, so I guess it works. It's a shame half the remotely mathematical items there are are multiple millions of sP like that, though. XD

I have no ideas (the gem plushies maybe?) but that's a spectacular pet name. ❤️
