Trapped Ring (Wit's End) Puzzle

thingiverse

The aim of this brain teaser is to remove the large ring, highlighted in red within the images. Assemble the puzzle as depicted in the first picture. The string merely needs to be around 10cm long, but a length closer to 20cm makes solving the puzzle less finicky. I initially encountered this puzzle on display alongside several others in a souvenir shop. After investing considerable time fiddling with all the puzzles they had, this was the only one I couldn't crack, so I decided to purchase it to be able to tackle it at my own pace. However, it wasn't situated on the shelf where all the other puzzles for sale were displayed, and when I inquired the shop owner she revealed that the man who used to craft them had passed away a few months prior. This meant they couldn't obtain any more units to sell, and the one on display was their last remaining one. So, having just assembled my first 3D printer a few weeks prior, I decided to take some photographs and attempt to recreate it. After dedicating quality time with the new plastic puzzle, I finally managed to figure it out for myself. Can you?
