Can YOU remove the ring??? (includes solution!)

prusaprinters

This is a medium-difficulty puzzle that I enjoyed solving many years ago!The goal is to remove the center ring. No force is necessary.I designed it primarily in Fusion 360. I printed it with Reprapper grey and Atomic purple PLA.Note for the original version: I used organic supports just for the tops of the pillars but later discovered they were not necessary. UPDATED and IMPROVED V2 version:No support is required! My new unsupported print turned out great! I made a few changes, including the removal of supports (I left the unused paint-on supports sections in case someone still wants/needs to use supports in their specific case), added variable layer height to smooth out curves on/within the pillars, and concentric fill on top/bottom of rings/beads. The entire puzzle prints in less than 4 hours using a 0.4mm nozzle and looks even better! Enjoy! Additional items for assembly:A MINIMUM of ~60cm (2 feet) of the free-moving string plus more for the knots. Longer string does not pose a problem other than the possibility of someone creating giant knots while trying to solve it! ;) I used this 4mm paracord as found here on Amazon, but a thinner cord may work better:https://www.amazon.com/gp/product/B095SVH1GK/?th=1&psc=1Melt the ends together (as suggested by @FreddyBee_466602), use hot glue, or tie knots to the base anchor and end ring. UPDATE (Oct 8, 2023): The SOLUTION to my puzzle has been posted as a PDF with pictures and a video link under OTHER FILES. Enjoy the challenge and good luck! Please share any makes and click “Like” if you like it!
