This is a fun elephant attachment for water taps, to turn it into a drinking fountain/faucet to help with brushing teeth or drinking without a cup. There is 3MF and STL files for every size tap from 15mm-30mm (diameter) in 1mm increments, so 15 different sizes total. The size that they are labeled are the recommended tap size, each file has a 0.1mm tolerance to ensure it fits. Measure your tap diameter and download the file that it relates to. If I don't have your size, let me know and I can add more files. They all print without supports very quickly, I used regular PLA, but may need a food/consumption safe material if it is something that you will regularly use. To use the device turn the tap on minimally (too much pressure and it'll turn into a hose), place the device over the tap and hold in place and cover the bottom hole with your finger (see GIFs).
