Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3685752.

i made this to hold my 40 oz tumbler, but i included a step file so it can be modified to put a base that suits your needs.

the design is made so that i can grab it from top where i put my finger into the handle and the projection off the top can give the palm of my hand support. or i can just grab it from the side like a regular mug handle.

i included a step file so u may modify it to different diameters.

needs no supports when printed upside down.
