Jar opener - any size
thingiverse
I designed this to make it easier to open Jars that are, well... hard to open. The model fits onto any 220x220 buildplate. I would have made it with four different sizes but then most of you would not be able to print it There's only two files you need to print: opener.stl: Should be printed in PLA or in PETG if you want it to last longer. Also make sure you print it with at least 2.0mm wall thickness and at least 35% infill. TPU part.stl: Should be printed in TPU and also at least 1.6mm wall thickness. As for the assembly, just glue the two pieces together with whatever you have lying around (I used hot glue), let it dry and you're ready to go. Edit 08/06/2021 I have added a version where the two pieces are combined for anyone who doesn't have TPU. You can find it in the thing files section under "Opener - one piece.stl". If you're printing this version, you might want to glue a rubber band or something else on for better grip.
