This heart-shaped puzzle is a small assembly challenge made from 7 unique pieces that fit together to form a complete heart. Each piece has a simple geometric form, but finding the correct orientation and order reveals how the full shape comes together. It’s a quick, satisfying puzzle that works well as a desk toy or small challenge to pick up and solve in short sessions.

The idea behind this puzzle was to create something approachable rather than overly complex. With only seven pieces, the puzzle feels inviting even to people who don’t usually enjoy long or difficult brain teasers. It’s designed to be solvable in a few minutes, making it a nice interactive object for desks, shelves, or small gifts — something you can hand to someone and watch them try to solve right away.

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.
