vacuum pump Pod and modifications

Found some great resources on the web. Using a HF Harbor Freight Vacuum Pump 3.0 CFM and some 3d printed pods. Some trial and errors. A lot of success and fun. 3d printed a HF Pump Vent to allow a 3/4" plastic pipe to be slipped in and the threads fit. Showing the use of a gauge to show leaks and wins. Tried various gasket materials some worked some failed.
