There are a lot of Yeti handle models out there. I like the two-ring ones that support the tumbler at the top and below the beltline. This one prints easily with minimal supports.
It screws together with a printed-in-place screw and it locks into place with a satisfying click.
Print it with your favorite “structural” profile with the rings on the build plate. Screw the two parts together and you're done!
Note - an earlier version was 10x too big. My apologies. I've also included a narrow and wide variant. My wife prefers narrow.
