This is a simple stand for a 3/16th inch dowel rod that I initially designed to use with a DIY foam board paint booth I made. These stands can be attached to the end of the dowel so it doesn't poke through the foam or damage whatever surface they're in contact with. You can also add an adhesive or double-sided tape, etc to the back so they can be held in place and used horizontally as well.
