Square pot mold V1 succulents plants napkins cement epoxy resign plaster

A square pot mold for a 3"x3"x4"tall pot. Pretty simple to use its held together with 1/4-20 bolts and press fit square nuts into place. I have used it for a few years to make pots for a restaurant in town. I do recommend silicone spray and even some packing tape to smooth the mold out. This is V1 of this mold I have a updated one out now for V2 way simpler to use, but decided to make this one free with my Freecad files
