This heart-shaped keychain fidget features a smaller heart captured inside a larger outer heart. The two shapes are interlocked at the top and bottom, allowing the inner heart to spin freely while remaining securely attached. The result is a compact fidget that can be rotated with one finger, making it easy to use on the go.

The idea behind this design was to create a small fidget that feels satisfying without relying on springs, sliders, or clicks. The spinning motion gives constant tactile feedback, while the heart-in-heart shape makes the object visually readable even at a glance. It works well as a pocket fidget, a bag charm, or a keychain accessory that doubles as something to play with during idle moments.

This design is also part of a personal challenge I’m doing for the year 2026: designing and releasing a brand new 3D printable model every single day for an entire year. Each design will explore a different idea—some practical, some playful, some reflective. If you enjoy following creative processes, testing new designs, or simply watching ideas turn into physical objects, feel free to follow along and join me on this 365-day journey.
