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.
Depending on the printer (CR-10 vs Ender 3) there are some other costs as well. Noctua fan ($14), 12VDC Buck ($10), Extension Cable for Extruder ($10). The prime cost driver is the E3D, with the cheapest legit I could find at $62.99. I think realistically, using cloned gears and legit E3D, one can walk away with the total cost around $120 (which is less than half of the DD Bondtech).
