Hello all,

I came up with this puzzle about four months ago in math class, I really hope that no one else has made something like it.

For some reason, the name "Pretzel Logic" (maybe spell it "PretzeLogic") sticks to it (at least for me.) Maybe one of ya'll might know where I stole that name from :lol:

The puzzle is completely comprised of tongue and groove mechanisms. There is only a single nut and bolt holding it together.

A cool thing about it is that it can make an additional cut on the top and bottom when the pieces don't block each other (as you can see in the pictures)

I still need to add tolerances/fillets... but before I do, I want to make sure no one else has made this

As far as I know, this hasn't been done (and since I compiled lists of all custom puzzles from 2009-2011, I do have a good idea of what's been done, though I don't quite have the catalog that Andreas Nortmann does). What makes this puzzle unique is that the two halves turn individually, as well as with each other, a feature that I can only recall seeing in the Fully Functional Siamese Cube set, though I may be mistaken.

The shapes of the round bits remind me of the Spin Out gray-code puzzle. I wonder if you could somehow combine the two...

Good to know that this is most likely an original design form me! :D

When I designed it, I realized that the puzzle is unique in that it can also behave as two individual puzzles (actually U.F.O.s (because of the 60 degree spacing) but it includes a middle layer the U.F.O. doesn't have) And unlike the U.F.O., it's restricted to only one axis to move the three pieces from one side to the other.

It would to cool to make it look like a space station or something and have U.F.O.s "dock" there and swap pieces.

Hmmmm... that gives me an idea if this puzzle works.

I forgot what the Spin-Out puzzle looked like for a moment, but I looked it up and got refreshed.

I see exactly what you mean, the way the rounded pieces can fit into the other ones. Good catch! If this works, that idea may be worth trying!

With a few exception my catalog is identical to the museum.
What you designed there is a puzzle with multi-origin-core, like these:

Ok, thanks for the link! Now I know what makes it special is the "multi-origin-core"

Andreas,

If you classify this (concept) puzzle as multi-core, then I suggest that you reclassify H-Cube, Fractal Cube and Twisty Tree as multi-origin-core too.

I did some seconds ago.

The system for the mechanisms steems from the time before CAD and shapeways.
On my TODO list is a big point "revamping the system of the mechanisms".
I do not know wheather "multi-origin core" will survive that process.
For now I just try to save the mechanisms "Unique" and "Unknown" from being overflooded.
