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.
but that's also not clear from the instructions. don't get me wrong, this is an awesome print, but the instructions (especially here, but also on the instructable) are a bit lacking.
and the filenames? The filenames are a disaster. tons of typos, inconsistent formatting, names that are too long (more than 30 chars) for makerbots and some other printers. it's not clear what you need to print, nor how you need to print it.
I did notice "Centerring_and_locking_cone" didn't fit flat on the bed before I printed it, so I switched to "Centerring_and_locking_cone__flatbase" and printed that. however, I did not notice the inside piece that would now be printing over thin air. and nowhere mentioned supports. so, that cone works, but the entire piece inside that puts pressure on the spindle is gone. luckily it didn't mess up the rest of the print, though it certainly could have. because the instructions don't say that part needs to be printed pointing down, I figured the extra space of the flat bottom one would give better bed adhesion, so I printed it that way first.
