About this 3D model

This is a puzzle box that you can cut on a laser cutter and assemble with no additional parts. The panels on the cube faces move, and if you move them in the correct sequence, you will open the box! This is an adaption of Bruce Viney\'s \"Cubey 2\" for the laser cutter. His original plans (requiring traditional woodworking tools) are here: http://homepage.ntlworld.com/bruce.viney/plans.html
