Felix Ure Titan puzzle

thingiverse

This is my recreation of Felix Ure's challenging "Titan" puzzle, reworked for ease and robustness in 3D printing. To prevent breakage, I incorporated modifications that make it easy to spin and less prone to damage if dropped accidentally due to its unique grip design. This model is not parametric without purchasing additional parts to enhance its functionality, and scaling it up would compromise its portability. Required components include: 1 x 608 bearing - I used a plastic shielded one, but thoroughly cleaned out the grease to ensure smooth spinning. 1 x .125" x .825" metal round rod - You can cut off the end of a drill bit or use a nail for this component. 1 x 1.95" (+- 0.020) x 8mm metal round rod - This was sourced from scrap linear bearings. 2 x 9/32" ball bearing - Finding these in small quantities may be challenging, but they can be purchased on eBay in packs of ten or more. To assemble the puzzle, print the four pieces and press the 608 bearing and .125" rod into Top.stl, ensuring the pin is flush with or slightly below the surface. Then, orient the remaining three pieces as shown in the picture and press them together, using a rubber mallet for the 8mm rod if necessary due to its snug fit. It's crucial that the two ball bearings and .125" rod are not magnetized to each other or the puzzle will be difficult or unsolvable. When fully assembled, the flat sides should touch without any issues. Edit: Felix Ure is the creator of this puzzle, not Hanayama.
