OLIVER RING - WOODEN STRING PUZZLE / Eureka

Saw this puzzle in a youtube video. Decided to make it 3d printable. There are two ways to assemble this puzzle: without the string loop (easier), and with the string loop (harder).You can begin with version one and then dissemble and proceed to the second one which is slightly harder to solve.I created two types of string ends. Type one uses rings which require slightly less rope, and require less filament. Type two uses full cylinders so a couple of extra inches of string are required. Also added a sphere with a flatter edge for better bed adhesion.Here is the solution to both versions if you run out of patience:https://www.youtube.com/watch?v=akigl5acZ_c
