Impressive work!
Thanks for the stimulation to try this with OpenSCAD

Just conceptual for me, whose printer is out of commission anyway, although I plan to make a couple via Shapeways

Fantastic print - makes me pine for a dual-extrusion setup! :-)

Escher would be envious :-)

I loved the prime tower lego & the write-up. Clever suggestion about using PVA for the support interface - not sure if Simplify3D can do this?

I'm not sure about Simplify3D but I've heard that Cura can do this. My concern is that sometimes PVA-over-PLA isn't a strong bond (which I think is a reason that the prime tower falls over), so the support interface might not stick well enough to the supports and you could have a fail at that point? I'll let you know when I try it...

Really Cool! I want to play around with that Topmod program now
