The file 'Twist Rhombic Dodecahedron Megastructure 3D Printer Model' is (skp,stl) file type, size is 1.0MB.
Lots of nested TRDs. SketchUp's Section Plane tool proved very helpful in finding errant interior geometry. Were there but a way in SketchUp to automate the finding and removal of interior faces and vertices!
More on how I made the print into a light sculpture here: https://plus.google.com/100359942295102553261/posts/hxKRGbCbemW
