Vacuum bag seal

Vacuum bag seal for snap lock plastic bags. Has a one-way value, easy print and assembly, prints on one plate with supports, tree supports recommended as they are the easiest to remove. Insert the small valve into the inside of inner cap, make a hole in the plastic bag to take threaded valve assembly and insert assembly from the inside. The hole only needs to be large enough to take the threaded portion of the assembly. You will need to use a good plastic glue to glue the inner assembly to the plastic bag. Use a vacuum to suck air through valve, continue until all of the air has been removed. Screw outer cap onto valve to complete seal
