accesorio cachimba dos mangueras

thingiverse

This device is a connection accessory that allows two hoses to be connected to the nozzle in one entrance, and can also be chained to increase the number of exits. It has two internal valves that work by gravity. The idea is to introduce a marble into each valve during printing so that it becomes sealed tightly (the purpose of the valve is to prevent air from entering the other hose when vacuuming, in case someone else is not doing it simultaneously).
