Puzzle: free (or lock) the ring

thingiverse

https://youtu.be/hsGLPamqVi0 Little brain teaser I used to create when I was a kid, brought back to life thanks to 3D printing technology. The puzzle can be printed with the ring already locked in place or in two separate parts. The choice is yours. Challenge: You have five minutes to remove (or reinsert) the ring. No extreme force is required; only your sharp thinking skills will do the trick! If you succeed, I'll be grateful and impressed by your intellectual abilities. If you fail, feel free to leave a small tip as compensation. For those who need help, the solution can be found in the video, but I have faith in your problem-solving capabilities. There are two ways to print this puzzle: 1. Print it all at once using 1_All_in_One_Print.stl. 2. Use 1_All_in_One_Print-v2.stl for a minor modification that improves printing quality. 3. Alternatively, print the puzzle in two parts: 2_facePart and 2_ring. I used PLA plastic, a resolution of 0.15mm, and an infill of 25% to create this puzzle. As you can see, no support material was necessary during the printing process. Enjoy!
