Picture Frame Corner Anchor

I have a cat that loves to swing picture frames back and forth, and out of desperation to be able to sleep past 6 AM I printed a bunch of these.

Slip a flat back thumbtack through the hole in the back, slip on to the corner of the frame and push into the wall when level.

One version for 22mm thick picture frames, the other for 14mm thick frames.

Also helps if you have room mates or neighbors who slam doors or bang walls.
