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.
It would be a little tricky because typically telescopes have an equatorial tracking mount, meaning the rotation of the rig is aligned with the rotation of the stars. While this could definitely track a particular star if you write the code to do so, it won't be able to track the rotation unless you mount the rotational axis to align with the Earth's rotation (look up "barn door trackers" for some guidance on how that's done). So basically, this would be great for tracking a single star's position, but bad for tracking rotation (roll) unless you mount it right. I am also interested in building this at some point for the same use case, so I'll figure that out some day if I get the time!
