Hand tools and fabrication machines
This adapter was developed by request of my friend Rami Wehbe , who wanted a way to play Zelda: Breath of the wild using only his left hand; as he lost the ability to control his right hand due to a cerebrovascular accident.
The Legend of Zelda: Breath of the Wild has a complex control scheme, and the shape of the included Joy-Con grip doesn't help at all. So, I decided to make a customized grip that would help in this situation.
This current design was the result of almost a week of research and lots of failed prototypes, as I had to ensure that it would be easy to print, lightweight and practical. After testing that it works properly, we decided to share it, so that it can be of help to other gamers in a similar situation.
