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.
Cool. I expect it'll work well enough, provided the prints are nice and smooth – which sometimes gets easier with a little break-in use, from what I've seen. You'd probably only have to print one or two extra pieces to try both ways, if you wanted to be conservative.
If it is smooth, a longer 3-wheel/5-gear (or 2-wheel/5-gear) assembly might look nice, to keep the balance.
Wish I could test it myself, but I'm not printing yet. My experience is in design, CNC and traditional building.
