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.
I modified it to print nicer vertically on my Cetus3D Extended, but it also might work for people with tall delta printers. Overhang comes out a little bit rough but not bad at all. They are the hit of my office... I can't print them fast enough now!
