I needed to hang a small painting in an exhibition, but the sawtooth hanger it had was not compatible with the larger hooks the gallery was using. I remixed the print-in-place hinge as a D-ring hanger that could slide under the sawtooth hanger temporarily during the show.

This part is designed for a sawtooth that has 45 mm/1.75 in width clearance. The framed pictures were 5"x6" and weighed less than a pound, so your mileage may vary as to how much weight the adapter will need to support.
