Main model looks organic but is not optimized for supportless print so be prepared for some defects if your printer is not well tuned for steep overhangs. Alternatively you can get ‘optimized’ version where overhangs are limited to 45 degrees, but it looks less organic :)

There are also options to have it as 3-part model with stem being printed separately and connected by squared peg (can be press fit or little bit of glue) or have it merged with lid and print it in a same color, or do color change mid print.
