Cylinder Puzzle

I did not design this puzzle, Wil Strijbos is the original creator. Version 2 of the puzzle has tighter tolerances and I added visual marks for easy location. Make sure that all parts fit together smoothly and rotate without obstruction. Additionally, ensure that the balls can pass easily through the Top Cyl hole. You may need to perform some filing or sanding to achieve a proper fit. Required components include: 5 pieces of 5/16 (0.313") ball bearings - start by trying two to see how they work 1 spring: https://www.mcmaster.com/9657k335 (I modified a spring that I had on hand) Note: The outer diameter of the spring needs to be no larger than 0.50" and its inner diameter should be greater than 0.32" You can experiment with adjusting the Z scale to add more balls, but you will need a longer spring for this. To find the solution, watch this YouTube video: https://www.youtube.com/watch?v=-kv2sTiPHsM On the original puzzle, there are locating marks that I did not include because of a layer seam used as a reference point. Let me know if you think it would be beneficial to add something. Please share any suggestions for improvements, as this is my first attempt at creating this puzzle!
