Venturi Vacuum Degassing Apparatus for use in Rapid Biomedical Part Prototyping

Step 3: Attaching the Vacuum hose: Drill a hole in the side of the container

Make a hole in the side of the container.

Instead of using a drill, you might consider heating the connector and melting your way through the plastic container. You might also heat the base end of a drill and melt it into the side of the plastic container. This will assure that the nozzle fits snugly.

When you have a hole in the side of the container, screw in the connector and then hot-glue or rubber cement the nozzle in place from the INSIDE.

This fitting has to be air-tight
