Flatland Lock

pinshape

The 3D Printed Lock Takes Its Cue from the Bank Raid Puzzle in Ivan Moscovich's "Leonardo’s Mirror & Other Puzzles," Which Itself Was Inspired by Edwin Abbott Abbott's "Flatland: A Romance of Many Dimensions." The Pieces of This Lock Can Slide Up, Down, Left or Right and Have Studs on Their Back Sides for Smooth Movement Along Channels in the Base Plate. Once the Top Piece is Securely Glued into Place, Four Corners are Fixed but the Frame's Sides Remain Open. The Goal is to Liberate All Four Pieces from this Frame. To Achieve Optimal Results, I Printed the Lock at 80% of Its Original Length and Width, While Maintaining Unchanged Thickness. The Following Video Demonstrates a Step-by-Step Guide on How to Successfully Solve This Puzzle.
