Mechatronics engineer Julio Vazquez has designed Joy-Con adapters that make the Nintendo Switch more comfortable for playing one-handed.
Vazquez has two blueprints available for download on his Thingverse page: the first is a shell that holds the two Joy-Con together, side by side, and its design is based on Breath of the Wild’s Sheikah Slate.
The second is more unusual looking, slotting the Joy-Con together at a right angle. Check out the pictures below:
Regarding the build, Vazquez said, “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.
