A flexi rex for your stanley cup!
This one if for the one with the handle on the lid, but I might make one for the one with the handle on the base in the future, though I don't own one so I'd have to look up the measurements.
Changes I made:
Took the flexi rex found at DrLex0 ‘s github and added a clip I modeled to it’s feet so I can shove it on my stanley.
Boost Me Boost this stupid little thing ( or the original flexi rex if you like this one and you haven’t. )
0.16mm layer, 2 walls, 15% infill just a default to get you by.
