Tiny under-shelf mount picture frame corners

thingiverse

I use a desk with multiple shelves above it, and I needed a way to hang pictures vertically underneath. These are small, easy-to-use items that let you hang pictures, artwork, etc. of almost any size on the underside of shelves, desks, cabinets, etc. Just attach a piece of double-stick tape to the flat part, push a thumbtack through the holes, and you're done. It probably won't hold much weight, but it should hold pictures or paper artwork just fine.
