48mm PET bottle adapter for water dispenser

The original cap has been adapted to a specific model I found on temu. You can see the model in one of the pictures.
If you wish to make changes to suite your own dispenser, here is a link to the Onshape document: https://cad.onshape.com/documents/98f25982e6a8f43fafb175d3/w/3daff50ea9a3946d3020e1f2/e/7849abcdd01560e66889181c?renderMode=0&uiState=696520ff7396e3d4632b0e82
Height (excluding cap), outer diameter and hole diameter are exposed to make for easier editing.

Thanks to Sim_26356 for the original cap model. I tried making it myself, but gave up to avoid headaches.
