The Radbox is a tiny puzzle box that can be easily opened without using any tools or external objects. It's designed to be printed in 8 parts (5 different) and assembled with or without glue, depending on your printer's tolerance level. Use it as a thoughtful gift and utilize the small compartment to hide small items or money. Solution Below... To unlock the box, roll it 45 degrees to the left and push the lid back further. In this position, the box is halfway unlocked. Then keep the lid in place and roll the box 45 degrees past the horizontal to the right, pushing the lid in the same direction as before. To make unlocking easier, wiggle the lid about 1 millimeter to allow the discs to rotate freely.
