Chopstick Ring
A finger-worn chopstick that flips from an eating utensil to a flat fold against your fingers in one motion — so you can eat lunch at your desk without getting food on your hands or your keyboard.

The problem
Eating lunch at a desk usually means a trade-off: eat with your hands and risk leaving food residue on your keyboard, or set your work aside entirely. Neither option is great when you're trying to get through the day without a break in focus — or in your meal.
The design
The Chopstick Ring lives on two fingers. A pivoting arm swings down into an eating position when you need it, then folds back flat against your hand when you don't — clean, out of the way, and always within reach. I worked through the geometry in CAD, dimensioned a six-part assembly, then 3D printed and hand-assembled the prototype with metal pins and rings.
Two positions, one hinge
The whole design comes down to a single pivot. Rotate the arm one way and it's a utensil; rotate it back and it's out of your way.

Pivot the arm down and the two halves meet at an angle you can pinch food with — just like a normal pair of chopsticks, except they never leave your hand.

Swing the arm back flat against your fingers and a pair of small embedded magnets click into place, holding it snug against your hand so it stays put — out of the way and ready — while you type.
