I downloaded the "Cadogan Upside Down Teapot" design for fun, to try out the upside down filling mechanism while ago and somehow went using it as my main watering can for smaller plants. I liked the design and size of it alot, but could not get used to the upside down filling mechanism. Inspired by the design I modeled a version with a opening on top, made the handle bigger for better grip and rounded corners for ergonomics and esthetics, optimized the model for printing without supports.

Have a look at the original bottom fill teapot https://www.thingiverse.com/thing:5209271 from https://www.thingiverse.com/povsky at thingiverse.
