Description

This is locking heart for your valentine! Features an innovative, unified, compliant 4-point latch system, making it fast to print and assemble. It is fun and functional, a puzzle and a way to give a small present.

The lid features a mechanism with four floating latches that slide into place, locking the centre sprocket. These latches lock the box shut and will only release when centrifugal force pushes them outward simultaneously. Each latch independently prevents the box from being opened, so only by spinning the box can all the latches move into their outward positions, allowing the lid to lift off.

It also features a folding heart handle which lays flat when not in use.

This puzzle box is perfect for small gifts or creating a fun challenge for the recipient. It’s an engaging blend of physics and ingenuity that’s sure to impress!

100% printed - no hardware, fasteners, or adhesives required. No support is required.
