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 print at .2 layer height then sand the parts to get them as smooth as possible, then use primer filler, sand primer filler sand then topcoat.
Same as you would repair your car but on a smaller scale. There are no real shortcuts that I have found that really work.
Hope this helps and if you decide to make it please post pictures. Good luck!
