This was made for the Anmiliy Hidden Door Hinge 6x2.5x1 on Amazon. It may work for others.

The first file does the main part of the routing, then the other file should be able to insert into the part you routed, and you can plunge deeper for the other part.

The third file may save you from having to print both of the main ones, as it is just the insert pieces. I haven't tested this one.

YMMV, test first, adjust, etc.
