Carrying an umbrella at all times without using your hands is now possible. A designer has created a 3D-printed mechanism that unfolds from a bracelet into a radial canopy 30 cm in diameter. The system uses articulated pieces that mimic the movement of a fan, offering portable shade for intensely sunny days without needing to carry a traditional umbrella.

The development is based on a structure of PLA-printed arms that rotate from a central axis fixed to the wrist. Each arm deploys a lightweight fabric membrane when a spring latch is activated. The 30 cm diameter allows it to cover the forearm and part of the torso. The design was optimized so that the assembly weighs less than 50 grams. Closure is achieved by rotating the arms in the opposite direction until they fit inside the bracelet casing, which measures 4 cm wide.
The invention that will make you forget about sunscreen (but not the wind) 🌬️
Perfect for those days when the sun hits the back of your neck while walking and you don't have a free hand to hold an umbrella. However, if the wind blows strong, get ready for the umbrella to turn into a sail and drag you across the street. It's also ideal for your friends to compare you to a terrace waiter or a walking floor lamp. But hey, you've got shade.
