Description

Four Pieces, One Heart

Keep your inner circle connected with this interlocking puzzle heart. This isn't just a static model; it’s a functional set of four individual keychains that fit together perfectly to form a complete heart. It’s a great way to use up those last bits of filament while creating something meaningful.

✨ Key Features

  • True Interlocking Design: The pieces use a classic puzzle-tab geometry, providing a tactile and satisfying fit when brought together.
  • Built-in Keyring Loops: Each of the four quadrants features an integrated hole for split rings or lanyards.
  • No AMS Required: Since each piece is its own model, you can print them one by one in different colors or materials on any 3D printer.
  • Pocket-Friendly: The edges are slightly filleted (rounded) so they won't poke you or snag your clothes while in your pocket.
  • Support-Free: Designed to lay flat on the build plate for a clean, easy print with zero post-processing.
