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’s been a while since I posted this design, so I just reviewed the list of files to see what you are referring to. There are many parts that list small, medium or large. If you review the included instructions, you will find that they are all needed for the build. The only items that I included duplicates of is the crank pin and crank handle. I included different versions of those in case someone wanted a looser fit like I did for mine.
I hope that your build goes well!
