Hexagon Head female stopper 3/4" inter diametre

this Femelle stopper designed using OpenSCAD , and it's modified from male stopper 3/4" from my first object shared here, it's nice cap for blocking wather in pipes or other used thing for male threaded pipes 3/4".

i hope the finish printed object work well , and before use it apply an anti-leak tap or epoxy on male threaded pipes or what ever for best result
