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.
This is unfortunate as your 3 way dice tower is outstanding. There always has to be somebody to spoil a friendly, cooperative community by only thinking of themselves. If they think they can make a business out of your designs (and others) that's fine, but pay the designers a royalty or a share of the profits.
This can only diminish 3D printing as a hobby, as IP theft happens more and more, less and less talented people will be willing to openly share their designs and everything grinds to a halt.
Hope you do well in the future.
