Summary

This is a fantastic puzzle!
It's not too easy, nor is it too hard to solve. It comes from the mind of a brilliant Japanese puzzle inventor called Osanori Yamamoto, whose Bisect Cube puzzle was one of the first things I uploaded to Thingiverse.
Not only are all his designs very clever puzzles, but many of them are also ideally suited to 3D printing as they require no additional support.
The puzzle consists of one ring shaped piece and four identical T pieces. These must be assembled with the Ts arranged in a mirrored pairing as shown in the photo.
The design was downloaded from the Puzzle Will be Played website at http://www.puzzlewillbeplayed.com/643Ring/FourMirrorOne/

Instructions

As usual, I have created the STL files with a small bevel (to remove sharp edges which can snag during movement) and a 0.1 mm offset (to give the pieces room to move). Each unit cube is 8 mm on a side but feel free to scale the puzzle up or down in size as you wish.
Do bear in mind however that the fit will get looser as the puzzle gets larger, and tighter if you print a smaller copy.
Print one of the ring pieces (S1) in one colour and four of the T pieces (S2) in a different colour. I prefer a medium infill and 0.2 mm layer height to ensure a nice smooth top surface.

No one can solve this at my school. Any hints? Tips? A video perhaps? We love it, but can't solve it… Maybe I need to print it bigger…

THANK YOU! Just seeing this... Great video. I appreciate you making it. I will try it out. No one has solved it still. And still not sure if the pieces will fit or if I have to offset a little more. Seems like the pieces are quite tight. But then again we could all be doing it incorrectly! Thanks again for the video!

Note to others: I printed this on a Replicator Mini with default settings and the tolerance was too tight. Then I tried again at 200% scale and it seems to work great now.

No, not yet. The only advice given on the source page (follow the link) is that rotation(s) are required. This means that the Burr Tools program will not be able to provide the solution. It can't be too difficult because I managed it!
Have another go and if you're still stuck, write again and I'll do a video.

Are there any tutorials on to solve this puzzle?

Is it just me? I try to download all the files and get a zip with the stl of the ring piece. Trying to download the other stl file gives me a screen full of gibberish.

Hi Fiacha
I'm sorry you had problem downloading this. I don't have any control over the zip file that Thingiverse creates so I have tried deleting both of the original files and reuploading them. I hope this fixes the problem for you.
