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.
This is a remix of the joshvv Flexible Filament Extruder Upgrade that I added M6 threads to the inside hole where the coupling attaches to prevent the coupling from popping out when not using flexible filament on the printer.
I had this happen once when printing PLA so this fixes that issue as the coupling screws in very solid now.
