The file 'Penrose Cube Illusion 3D Printer Model' is (stl) file type, size is 205.5KB.
This is an extrapolation of the now infamous Penrose Triangle illusion 3D model (http://www.thingiverse.com/thing:6513). If you had trouble getting your head around that one, you're not going to find this one any easier! :)
Where the triangle used 9 cubes, this arrangement uses 31 cubes to make a larger sorta-notreally-cube.
All versions are parallax-corrected for a viewing distance of 40cm.
(the larger ones are not simply scaled up versions of the smaller ones)
