Jar Opener
thingiverse
UPDATE! - Version 2 now includes an additional layer as per my comment at the end of this text. I highly recommend using this version. I have since updated the model with some significant improvements, replacing old files and adding a new cut-out section done at an angle to ensure all levels align perfectly when closed and inserts are perfectly symmetrical. This project was inspired by my daughter's complaint that she couldn't open a jar one day. I remembered the Universal Bottle Opener by In3Designs (https://www.thingiverse.com/thing:3057772) and decided to create something similar. The design requires a flexible type filament, such as TPE or TPU, as an insert to grip the smooth metal lid. For any intermediate jar sizes, the unit can be pulled open slightly. The unit will fit on a 220 x 220mm bed at 45 degrees. I am considering adding another level between the top and second from top sizes. I would greatly appreciate any feedback since I created these sizes based on jars initially found in our cupboard and fridge here in Australia, and I am aware that jars come in many different sizes.
