We designed models for devices that can assist people with arthritis. The Mouse Holder and Wrist Support allow for a better more comfortable use of computer mice. The openers allow for an easier time opening jars/bottles/cans without putting lots of stress on the joints. There is also a one handed controller device with people with one hand.  

We recommend printing the openers in PETG for longevity and strength though PLA will work too. The infill should be around 10%-20% for a flexible but strong print. A penny is needed for the bottle opener that will be put into the print with the penny top part put over it. 

The mouse holder parts can be printed in PLA or PETG and the wrist support should be printed in TPU for maximum comfort but PLA also works. When printing the Mouse Holder use at least 5 walls for printing. There is also a larger Mouse Holder if the normal one is too small.
