Triangle Ring 3 Puzzle.
Boys and Girls,
The only ring I detected was the ringing in my ears as I tried to conceptualise the box enclosing this puzzle. Did someone say that puzzle word, “magic”?

After tackling it in SketchUp, it seemed relatively simple,
however, after assembling a prototype MDF of it…
Yep, back to MDF... I now understand how Confucius managed to rain over the Roman empire… and no, I didn’t use a stretchy form of Kodak film.
Another evolution in my design, carried over from my Eggplant Puzzle, is the extended fingers as can be seen from the above SketchUp screen dump… the box’s thickness is 3mm and the fingers protrude by another 3mm. This permits laser cutting out of 3mm to 6mm material… the thinner the material below 6mm, the more of the fingers that need to be sanded off.
Just to prove my point, I used the same unmodified laser files to cut another box out of 6mm MDF… just upped lowered the speed (power was at 100%)...
the only sanding I did was to sand off the laser burn marks on the fingers’ edges… being level with the surface, this just provided smooth sanding to all sides. The open edges were scraped and manually sanded clean on the 6mm thick box… forgot on the 3mm.
Used the advertising brochures to reverse engineer the “cubed” puzzle pieces,
Set up my reverse mitre gauge TS method as detailed in the Eggplant Puzzle project and cut enough cubes for 4 solid puzzle
tested for fit in the MDF box
Also designed for a laser set, cut from 6mm MDF 2b laminated,
Colour included for doco purposes as my laser cannot cut and colour, even MDF.
Colour removed and parts reorganised to minimise waste for cutting purposes, and lines coloured for cutting sequence priorities,

The 3mm MDF box was initially made to ensure puzzle pieces fit and the 6mm MDF box was cut as a POC… damn, I had to make 2 sets of MDF laminations,
Then it was walnut time… and not to forget cleaning up the edges,
engraved the base before assembly,
MDF versions already assembled
it was a PITA to stand the box up (for engraving) due to its instability (shape).
The box was dry fitted to optimise grain orientation (another awkward PITA) and labelled,
for future assembly and a reference for buffing the opposite inside layer of each side.
A tad disappointed with the backfill. I used white Timbermate and that mixed with the charcoal of the cut and the buffing waxes (orange Tripoli), didn’t result in the expected contrast,
unlike the MDF,
As the logo is designed to be on the bottom, a quirky fact about this puzzle is to assemble it with the symmetrical box upside down,
because the last move in the solution is to push a piece up from the bottom. Unfortunately when the box is picked up, gravity puts up (down) its hand and the piece drops,
So when stored using this assembly methot, with the bottom down (as designed), the piece drops “up” and the puzzle is more manageable in the hand,
I know what I mean!...
As always, the 3DW model,
Anyone interested in my puzzles (or other authors’), you can see them all here in my “Puzzle Collection” .
If interested in any of mine (LBD), measurements can be made available on request for anyone not familiar with SketchUp… though a working knowledge of SketchUp’s navigation (not its design/use features) and access to 3DW could be of benefit.

looks impossible to solve.

To complicated for my ancient brain. Is a good one.

Petey and CMLXXXVII, you sell yourselves too short, however, the joy is in the frustration derived from the recipient... one needs a slight mean streak.

Super mind boggling!!

Has to addle the brain just building the things!
Cool "box" design!
Only fill that I've found to have any reasonable contrast on walnut is pure white, usually need to make all the lettering fatter as well. Maybe a neon fill is available?

I really appreciate that the solution is provided. Without that I'm not sure I would tackle any of these. I need to wait a few years for the grandkids to get a bit older.
Again, thanks guys...
Splint, unfortunately not my design... no where smart enuff, I just plagiarise them.
The shape of the box had me going for a while... orient it in the X/Y axis and it was OK, ignore it and I lost track of which side had been sanded/buffed after the 1st. pass.
eRasmus, if you get the urge, you'd better start now... those little suckers grow up quicker than you realise... hell, soon they'll be older than you. Stockpiling sure beats the pre-Chrissy rush.

The think I really like about this puzzle and your eggplant one is that they are not only diabolical torture devices, but also attractive desktop structures. I especially like how this one looks. The use of hardwood elevates the look compared to MDF.
I've never looked at your "4D PDFs" before. They're very impressive pieces of technical presentation.

Thanks RS... No question the solids look better than MDF. Unfortunately the price of solids vs MDF makes freebie handout a tad untenable... the other benefit of MDF is that it comes at a constant thickness without the need for dressing, for repeatability and mass production.
The PDF's are the result of the SU model... The SU model has the solve/unsolve steps in scenes, however, not everyone know SU and those that do, don't carry it around in their back pockets.is easier to

Speaking of MDF vs. wood, do you have to take wood movement into account? I’m sure those little cubes don’t expand very much, but it looks like they fit snugly into the box.
I thought you sold your puzzles. If you’re giving them away, I see why you prefer MDF for fiscal reasons (in addition to the uniformity you mentioned).
I like to use lots of scenes in my models. I don’t take care to add clipping volumes around them. I suspect more than one viewer has opened one of my models and hit the zoom-all icon and concluded I’m a total idiot when they see little clumps of geometry spread all over the place.

I use layers extensively and overlay groups/components over the same spot... only gets confusing when I do a "show all".
Rechecked you thread... sneaky, had me fooled at first glance...
Just as an FYI, I use this plugin.... has served me well... great for STL creation.

LBD they are very cute but torturous to figure I suspect. Well done they look great.
Kerry - Working with wood, the smell the feel, is such a joy, its a meditation of sorts.
Thanks AL... I'm no masochist... unlike those bought online without solutions (for a small fortune), I include a link to the PDF solutions in the instructions... I just put in a dodgy piece so it can't be solved.
