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.
Sorry, not sure what you mean, but let me clarify what I think you may be referring to.
Assembly: The magnets are glued in the holes provided - once. They become part of the plastic pieces - they are not coming out.
Play: You brake apart the model and put it back together as many times as you like.
Does this help?
