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've just uploaded a new thick-walled mesh version here: https://www.thingiverse.com/download:6099241
Please try it out - if it works on your slicer, I'll update the rest of the files.
A stronger mesh will certainly help stability, too :-)
