This is basically an adjustable hole which lets you adjust the pressure by setting how much air leaks into the vacuum chamber/bag. I have combined this regulator with a fridge compressor and a vacuum gauge. This makes the setup as capable as a real vacuum pump.
Having a “perfect” first layer is important, you might need your nozzle slightly closer to the bed to avoid air gaps. Print on glass or smooth buildplates. Sand the interfacing surfaces of the Main Spur gear and the Base. Use 400 grit sandpaper on a piece of mirror to fully flatten. Use some kind of grease on the interfacing surfaces to make it smoother and air tight.
