This is based on a puzzle patented in 1906. I had to modify it a little bit from the diagrams to get it to work, but I think I kept the spirt of the puzzle. Puzzle Master also sells a version of the Dorstrom Hub puzzle here. There's a review video and solution video to that puzzle to see it in action.
Printing Instructions
Print all 6 pieces in the provided STL file. Should be a fairly easy print. No supports required.
Assembly Instructions
Assemble as in the below digram, sandwiching the 3 hubs between the two discs. It held together fairly well for me without glue, but you could glue the discs together to make it more sturdy and make sure no one cheats! You might want to solve it a few times before gluing it together though!
IMPORTANT! The middle hub (yellow in the digram) should be flipped upside down compared to the top and bottom (red) hubs. In the STL file, I laid out one of the hubs already flipped so that the textures will look the same across all 3 hubs.
Adding the Rectangular Ring
I would suggest assembling the hubs and discs, and then try to add the ring after it has been assembled. That way, you know it will be on correctly. If you want to put the ring on during assembly, then try to remove the ring before gluing things together (you may not even need glue). Make sure one of the short ends of the rectangular ring is sandwiched between the pill-shaped slots, and the other short end diametrically opposite. There should be 4 spokes on each side of the ring.
