MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Keep printing and I'll keep making more! I also have a few printers, but I tend to do most of my printing on one machine at a time. Personally I think that the model assembly process adds a nice dimension so that you are more engaged with the 3D printing process rather than just printing out full models. My 'no supports' direction is due to the fact that I very much dislike supports and the print failures that accompany it.
Actually, Wizard of OZ sounds perfect. I keep a list of all maker suggestions and try and work off that list. Interestingly enough Wizard of OZ has not been mentioned before.
FYI, I have two models that were taken down on Thingiverse due to copyright issues. Those two models can still be found on MyMiniFactory.
