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.
The holes are only guides. The diameter of the holes is 1.9mm so is aprox. the same as standard filament. You can use your filament as a pin (if you print at the current scale). I'm gonna update the description of this model. Thanks.
