A few days ago when I was looking for inspiration I found this seemingly impossible ‘remove the ring’ challenge!

My instant opinion was that it was fake, but I had to test it out, and IT WORKS!!!

it took me a few tries to get it right but I eventually got it, this video shows how it's done and can be misleading at points but with a bit of perseverance you'll get it right!

I made two versions one print in place and one separated, the separated one is much stronger but takes more time and needs string, the print in place one is ready off the print bed but sadly is a bit weaker especially with all the frustration and rage that these puzzles fall under. I've designed the ring so it can come off with a bit of force so that it can't get it permanently stuck, however if you want it to be impossible to cheat you can just scale the x and y down to 70%

Print them all with normal settings

Enjoy:)
