Vacuum valve complete from the 3D printer

Vacuum valve which comes 100% from your 3D printer. Mandatory supplement for your cyclone separator, without it your container can implode. Since every vacuum cleaner performs differently and the materials used also have different springiness, I have created several versions of the springs. You just have to test for yourself which one works for you. The following applies: the thicker the spring, the later the valve is triggered, so start with the weakest one.Use it to provoke a clogged nozzle and see whether the valve triggers as desired. As soon as the valve no longer triggers, the spring is too strong! assembly is very simple: Put it together like in the photo, then pinch off a 5mm long piece of your filament (Ø1.75mm) and insert it into the spreading finger. The hole for the valve should be between 48mm and 50mm. (hole saw) Seal the valve and insert it, screw it from the inside... done! If you want to improve the sealing surface of the piston, you can cut and attach a soft rubber or
