Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4526877.

i got the idea from a video here: https://www.youtube.com/watch?time_continue=53&v=asCGdnVlXyg&feature=emb_logo

mine is made to hold a 40 oz tumbler.

the top can come off if you dont want it on, and just use the ergonomic handle.

i included a .stp file so you can change size to whatever you need.

the top spillnot comes off via a camming pin which hold it secure to tumbler handle.

the pin has a flat along its length for easier printing.,

easy to print but does need supports.
