In this video I will make an even more complicated and difficult to solve maze bolt puzzle. I started by designing all of the parts in Fusion 360. Then I 3d printed each part using a plastic called PLA. Next I coated the 3d printed parts in a special ceramic slurry called Suspendaslurry. After that I placed the shells into a kiln and fired them at 1500° F to turn them into a ceramic. I filled the shells with bronze consisting of 92% copper and 8% tin. Once cool I broke off the ceramic shell molds to reveal the maze castings. Next I cast the bolt heads in a special sand called Petrobond. Once cast I machine all of the pieces on the lathe and milling machine to fit together.
