Opening and closing tool for Pyrex screw caps used for various test tubes and bottles in schools, laboratories etc. It's ergonomic shape and increased diameter reduces the required force for opening. This can be helpful for e.g. people with arthritis.

There is currently only one size available: thread size 42 mm.

My personal print settings

Material: PETG
Layer Height: 0.2mm
Supports: none
Infill: 25%, cubic
Perimeters: 6
Top/Bottom Layers: 5/3

Feel free to check out my tool for chemical canisters lids (which can be a pain to open too). It follows the same design approach.
