This is a remix of boltsnap's replacement Ikea Milsbo corner mount for flat screws.
It has been beefed up and extended a bit. I've added the counterbore found on the original OEM part as well so it fits more snugly with the cabinet's female threaded mounting stud.
The STL is already oriented in the optimal position for printing.
The author remixed this model.
The mount has been extended a bit and a counterbore has been added.
