Twisted Torus (soluble supports torture test)

A small torture test for printing with soluble supports. The inside of the torus is hollow, but the holes on the surface are quite small. This geometry was created to see how well PVA dissolves in hard to reach cavities.

The print in the photo was made using PrimaSelect PVA+, which in general did dissolve, but left some fine strings inside the geometry and especially around the holes.
