For those with portable projector screens, this is a replacement foot that you an use. I have had this screen for many years and some how one of the foot pieces is missing. I maybe used this screen 2 times a year. Finally made a replacement part.

Print this part with the flat on the bed, really does not need supports but a raft helps. You will get some hangers inside the cavity but since this is not a decorative part, just cut them off and insert onto the metal legs of the screen. I used PLA at 8% fill.
