Magnetic Adapter Plate for "wall-mountable-hand"

I inserted two magnets into a piece of furniture (a rack), and now I can put this adapter plate on top of it and connect the wall-mountable-hand to it. :-)

The magnets I inserted into the adapterplate are 10x10x10 Supermagnets.
And I put the same into my rack.
Distance between the center of the two magnets within the plate is 40mm.

I inserted a BREAK into the GCODE at the point, were one can insert the magnets into the partially printed part. Make sure to fully insert the magnet into the cutout, because when continuing the print the next layer will close the pockets. A collision of the printing head will stop the pruning process.
