Elongated picture hanging hook

We have a series of picture frames that were very hard to wall-mount, because the sawtooth were recessed over 1" / 2.5 cm from the back of the frame. So I made a wall-mountable hook that sticks out 25 mm from the wall, and is easier to slide into the sawtooth hanger.

The mattes and frames were purchased over 10 years ago, but my best guess is that they're from the “Ikea Ribba” series.

How to print

The included “recessed-hook-settings.3mf” file includes my settings for printing with PLA, (0.2 mm layers, extra vertical perimeters, and a bit of organic support) on a Prusa Mk3s.

If configuring it yourself:

• Since this needs to support some weight, you'll want the layer lines to run vertically when installed, so print it on its side with the “v2” facing up.
• I also increased all the perimeters by 1 from their default values. (At that level, there's not much infill to worry about)
• You'll probably need a bit of support for the tops of the screw holes and for the fillets on the build plate.

How to wall-mount

Fasten the hook to the wall with an appropriate screw, using drywall anchors if necessary. The hook should be facing up, but it does not need to be precisely leveled

Lower the sawtooth hanger down over the hook, and slide it left or right until the picture hangs straight.

Alternatives

1. Just use a screw that sticks out an extra inch from the wall (I didn't have any wood screws of this size)
