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.
As designed it uses a GT2 x 12mm wide TPU belt. This width is not standard, I doubled the width to try to help reduce stretching. However, if you want to use a standard GT2 x 6mm wide belt commonly used on printers just use this pulley set instead: https://www.thingiverse.com/thing:2847297. I'll updated the description with this information when I get a second.
