I fixed a recycled wood shelf my wife bought at a Salvation Army using my 3D printer. The shelf was missing a way to hang the shelf so I designed a custom insert using Tinkercad. This allowed me to hang the shelf flush to the wall with a couple screws.

These are custom designed for this shelf but may be useful for something else that needs to be screw and slide mounted.
