    I would like to make a fully printed spigot for a rain barrel. This is my first attempt and it is far from water proof. I know that I could add rubber rings to 2 or 3 locations to make it fully functional and waterproof but I am curious if others have a design that will work with PLA and no additional parts.

    Feel free to start with my design or come up with something entirely new and different. A design using ABS is fine but continuing to use PLA is preferred.

    More Information: I created a second design (Spigot II). It is generally the same but it allows me to print it such that the layers for both parts are in the same orientation. I also made this design very tight on purpose, too tight. I printed with the tip hotter to allow for better adhesion between the layers. I also sanded things to make things smooth. To made a long story short the thing still leaks. with the spigot in the closed position with very little pressure drops of water still leak.

    I don't think that you can make it water proof without the use of rubber rings. You can make the surfaces smoother if you use acetone vapor (with ABS obviously). This way you will minimize the roughness and the gaps between the 2 parts. Also you can try waterproof grease between the two parts.
