I printed the original and could see the facets in the model, so I made a higher resolution OpenSCAD version. The scad allows you to parametrically specify the tolerance between the parts.

Great, I'll try this one out later. 8-)

We do need an impossible heart puzzle Greg ;)

I was trying an impossible Stephen Colbert head :D

Awesome! I didn't have the original source files and simply took the STLs from the cube for my version and unioned them with a sphere. I venture to guess this one prints a whole lot better and fits better. Let me know how it comes out when you print one!

Ok I couldn't resist and sent it to my printer. Needed to clean-up the inside faces slightly - and it takes a lot more fiddling with to get it together - but it does fit together nicely once cleaned up (the little angular surfaces are the hardest of course). I also didn't slow the print down on my ToM and printed @ 60 mm/sec. Slowing it down a bit might have resulted in smoother angles. A couple surfaces could use a little bevel but nothing a needle file can't knock off quickly.
