Toroidal Polyhedra
thingiverse
McCooey's "Visual Polyhedra" site - http://dmccooey.com/polyhedra/ - includes a collection of Toroidal Solids. Coordinates and faces are given so that it is simple to print 3-D versions using openSCAD. Here are 4 easy to print examples which do not require support. Three of the solids contain a single opening; the fourth, "RM{4,6}_sub_10.stl", is a regular skew polyhedra with multiple holes. See the openSCAD code which includes references to the "Visual Polyhedra" web site.
