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 design requires smaller wood screws (M3 or M3.5) for the cable clips, and the power supply mounts. These screws should be listed in the list of required parts but they aren't.
The recommended right angle heat bed part isn't great on the MK3, most of the comments say it won't fit and that the cable can obscure the build area causing prints to fail. The description recommends bending your pins and stuff which I didn't like. I printed https://www.thingiverse.com/thing:2890592 instead. I haven't tested it with large prints, but at least it doesn't require mangling things and definitely works on the mk3.
The design makes no mention of attaching the bottom table, I used these: https://www.thingiverse.com/make:587706 they work great.
As I was using the 60 degree adapter the power cables were too short for the printer to be moved forward enough to not crash into the back of the enclosure, I solved this by drilling through the table and running the power supply cables through the hole.
