I designed this to remove the stubborn tops on HydroJugs. It is a simple design that works great, no more needing the oven mitt for additional grip. There is a hole in the bottom for to hang out of the way. I tied a string to mine to make it easier.

I may have overdesigned this for strength and durability but I would rather design outside the margins so it does not break while in use.
• Material: PETG or ABS
• 0.2mm Layer Height
• 60% infill - Cubic
• 4+ perimeters (I used 6)
Due to the heavy rounds on the edges for comfortable use, I did enable supports. It ended up coming out like a standard brim under the rounds.
