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 printed a bunch of these (PLA) when I first got our printers (Replicator+ and 5th Gen Replicator). Some broke right away, some lasted quite a while. My students love them - great motivators! I did find that it is best not to store them in the load position, as they tend to stay down and not shoot well after a short while.
I thank you for the files!
