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.
Read psiho's post and instead of scaling the parts so they fit better, I increased the perimeter extrusion width to 0.6.
This made the prints more rigid and slightly larger so they fit really nicely with no skipping of the notch over the puzzle walls.
I'm printing 15 of these to put my nieces and nephews Christmas gifts in. It should be fun watching them try to open them up!
