Ergonomic slip-on handle to fit various brands of tumblers/mugs by simply adjusting scale of print. This can also be taken into account when adjusting where the final position of the handle is snugged up on the mug. I’d recommend only adjusting scale in 0.5% increments, as the angle of change towards the top of the mugs become very slight. The shape of the handle also accommodates the clearance needed in many vehicle cup holders. Enjoy!
