thingiverse

Chinese ancient educational toys, renowned for their ingenious design, were attributed to a master carpenter named Lu Ban, who was said to be a wise and forward-thinking inventor. As part of his "Ming lock" series, which consisted of intricately connected mechanisms, one puzzle in particular, called the KongMing Lock or "Burr puzzle," showcases an array of 18 components that rapidly engage and disengage from each other with increasing difficulty. For makers looking to create this impressive mechanical puzzle, downloading a 3D model in STL format or GCODE file prepared specifically for the Ormerod1 printer is recommended.
