The insides of the parts needs to be coated with varnish for them to be airtight.

The diaphragm should be flexible everywhere except the middle. Two rubber sheets glued together with a 20 mm diameter plastic or metal disc in between works well. The diaphragm seals more reliably if there is a spring on top.

The two parts are held together with m6 bolts with a gasket in between. The nuts can be melted into the plastic.

Material: pla

Settings: Completely solid part. Better to use more walls than infill
