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.
It will use all the stock hardware, except 4 screws to attach the two halves of the printed mount together. For that you'll need either M3 screws with nuts (approximately 35mm long if I recall) or some self tapping screws that will thread into the printed part. I had some that threaded into the part nicely, so I ran a small drill through the thinner half (motor side) so the slipped through freely, then threaded them into the other half. The limit switch will attach to this piece in place of the original part, using the hardware from the stock parts.
