Water dispenser for birds with PCO1881 thread for PET bottles

thingiverse

Water dispenser with 5 drinking bowls and rings for fixing ''landing and sitting twigs''. At first I was going to make the design with outer bows or perches, but decided otherwise, as I (if I were a bird) might feel more comfortable on a twig... The thread fits perfectly, however, the sealing lip is not printed, because it is too thin. With me, the connection was nevertheless watertight, but you can also still use a sealing ring, which you can cut from the seals often used in the lid of beverage bottles. It is usually found in caps without a sealing lip, for example in the small bottles of one of the large cola producers here. Caution: be sure to print with the correct shrinkage correction, otherwise the thread will probably not fit or will be very tight. For me, this was 0.8% with the PETG from Verbatim - depending on the setup and material, this value could be different for you. A small note on hygiene: please clean the dispenser and bottle carefully on a regular basis to prevent them from becoming a breeding ground for bacteria, fungi or viruses. small addendum: In the meantime I have learned that PCO1810 is also often used for bottles, which has a slightly different geometry in addition to a different length. The PCO1881 thread fits nevertheless, however this is possibly very stiff and hard at the limit...If you want to use a bottle with PCO1810, or you are unsure, then increase the value of the shrinkage correction to bring more clearance into the connection. For me, this worked perfectly, so I did not make a second version. In this case, you should definitely use a sealing. For a test print, I would simply exclude the water bowls in the slicer from the print, then it will also print quite quickly.
