This is the rear Anet A6 plate in two parts that fit together. The Y motor mount holds the parts together.
PLEASE NOTE: I have not printed this yet. Only made the design and had no time to print this yet. If you do, please let me know your findings and I will adjust accordingly.
The plate is in two parts or it would not fit the buildplatform of the Anet A6.
There is also an "all in one" part to print that would fit the buildplate but is smaler than the original.
