Half Hour puzzle
According to the time stamps I actually made and filmed this puzzle last May so I guess I'm a bit behind the times. It's called the Half Hour puzzle and it's designed by Stewart Coffin. There's a whole bunch of 3D printed puzzles available on the puzzle hub website , I'm currently going through them looking for some inspiration for my next puzzle box. This one was a fun little build and I'm pleased with how well the pieces fit together for a first attempt. ( stl here )
