Heartbeat Grid Key Tray

Inspired by an optical illusion created by Akiyoshi Kitaoka, this unique key tray brings the illusion of a heart floating above a grid of lines into the physical world. The design, with its intricate texture and shading, transforms the classic black-and-white illusion into a striking 3D model. For the strongest illusion effect, use black, white, and gray filament, ensuring the gray is perfectly balanced between the black and white. To personalize the design, you can experiment with bold colors for the heart while keeping the black-and-white grid for an illusion that remains both striking and effective. The design is visible on the inside and bottom of the key tray. The key tray measures 220 mm in diameter and 25 mm tall, making it a perfect balance of form and function.
