This is a GREAT model and thank you for sharing it!

Has anyone successfully printed this on a Robo 3D R1? If so, I'm curious as to what your support settings were. I took the advice of an earlier post and used Meshmix to calculate supports (started with Part 1). Meshmix made this cool little tree-like support, but I had to cancel the print about 30% into it because the tree support failed, i.e. Robo 3D was trying to print it, but it ended up as strings between the support and the actual model. I wanted to save filament by using Meshmix as suggested, but maybe I'm doing something wrong. BTW, I'm using PLA in 0.2mm layers, two shells, 10% infill (hex), and the Meshmix support.
