Bill's Baffling Burr

Simple supports, ready-to-use.

6-piece level-five burr puzzle designed by Bill Cutler. Level five means that five separate shifts are required to release the first piece when the puzzle is assembled. This puzzle is more challenging than the solid burrs (like burr no. 306).

The solution is included but I recommend solving it yourself! The six pieces assemble into a burr as shown in the photo.

This puzzle has 0.2mm sliding tolerances. If you want to change the size or tolerances, download the f3d file and open it in Fusion 360. In Fusion 360, top ribbon>Modify>Change Parameters and change the values to fit what you want!
