I wanted a way to hang pairs of shoes on a wall or door, so I made this. The design is straightforward and should work on most printers without needing rafts or supports. I designed it to use with two sided wall adhesive strips, so it would be removable. I use the command strips (as seen in one of the photos). The height is such that the tab for the strips will hang slightly below the shoe mount, so they can be removed if needed.
