Venturi Resin Sprayer

Yesterday i was looking for a polyurethane resin sprayer to hard coat some Styrofoam props and i didn't find one in my country so i made my own.

This spray head fits a standard cheap EINHELL air gun and uses standard 6mm soft silicone aquarium air tubing for the resin supply.

Print with pla for resistance to acetone cleaning.

It uses an 80mm dia. plastic cup as a resin container for easy clean up and refill.
