The file 'Watering Connector For PET Bottles 3D Printer Model' is (stl) file type, size is 1.4MB.
I needed a watering for my garden, so I decided to search and print one in thingiverse. It didn't work, the holes were so big. So I made my own watering connector, it has small holes (1mm) and fit perfectly in a PET bottle. The water is nicely spread so you will not harm you plants.
