Used the initial CAD file to add this bottom Frame.
This set of files are meant to be used together in addition to the Brick Skirts by Kanrog https://www.printables.com/model/539461-plate-for-rook-mk1-mk1
I mirrored the base of the feet from the CAD design for the Rook to act as a ‘key’ for the Mk1.1 bottom frame. There's also a small amount of tolerance for fitting under the Z-motor mount.
I printed the ShortFoots in TPU
You will need longer bolts than the default, I used M5x30mm and they have about 3mm of engagement.
