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.
Answering myself, yup, the motor is way higher than expected (and I'm not even sure the heatbed can home with such a high nema17 mount) so I went ahead and remade the thing as a .scad file (not really parametric but should be enough to make modifications).
Your update is nice tho, I "merged" some of the new changes (smaller base, larger slopes, thinner nema mount (gotta find that stepper dampener again now :^)).
Thanks again for the design :)
