Blogger Kathy Hamaker posted this cool 3D printed puzzle that was built by her son, based on a wooden puzzle made by one of her ancestors. The design files aren’t posted, but we think this is a neat and fairly simple project that most beginning 3D printer hobbyists could tackle.
One cool aspect of the puzzle is that there are many solutions, so you can create a variety of patterns. Kathy’s son also created a cover for the puzzle to keep the pieces from falling out.
