A modern rectangular vase / pot that can be mounted on the wall.

My wife asked for a wall mounted vase to decorate her office--so I made this for her, and she's been extremely happy with them. Interior volume is about 9.25" x 5.25" x 5.25". I designed it to fit these brackets I picked up on Amazon: https://www.amazon.com/dp/B0CDH1BM51. (I used a mix of woodscrews and drywall anchors to attach them). A simple #8 screw keeps it close to the wall and a narrow profile.

There are supports underneath to allow the brackets to be sunk and less visible, don't add supports for the bracket holes themselves.
