Hey,

To my knowledge, a cubic 1x2x3 cuboid has not been made before. If I'm wrong, please correct me. Here is my attempt at making a 1x2x3 cuboid. I designed it to be the same cubie-size as a regular 3x3x3. It turns VERY well, and is actually kinda fun to speed solve :) If someone wants to do a quick count for me and figure out how many possible combinations there are for this, that'd be cool.

Video demonstration

Very nice.

Also, I could have sworn I've seen one before. I know for sure I've seen Jin's sketches many times though. :P

I've never (successfully) built a mechanism, but somehow I want to build this one. It just seems so gratifying, so satisfying.

Oh shoot, look at the date! I've got only 10 days to finish my next cube project.

But I just can't take my eyes off this one...simple, elegant, nonfat.

One "edge" ist assumed to be fixed.
4! possibilities for the corners.
2 orientation for the second edge.
=> 48 possibilities in total.

Scott, would you please share the internals? What's the mechanism? I am interested in your offer in the other thread, but would like to know the details first. Hope that's not too much.

Wow great Scott!

Is it a 100% handmade mechanism or an modified one?

I'm sorry to burt your bubble but someone did build it before but it is not cuboid.

http://twistypuzzles.com/cgi-bin/puzzle.cgi?pid=881

I'm sorry but I searched and I couldn't remember who had a picture of one thats post somewhere on one of the 2 form I think. It would be General Topics or Puzzle Building.

That puzzle isn't what I'm calling "cubic" It kinda looks like a football. As for the mechanism, it's very simple. The middle two pieces, are a 1x1x2. The the corners each have half-circle "feet" sticking off the bottoms, and they slip into a circular groove on the 1x1x2. It's exactly the same as Ton's 2x2x4 concept. And yes, It is a completely new puzzle. not a mod.

Member guoguo already made one a few months ago. See viewtopic.php?p=90302#p90302. But Scott's looks superior.

Shoot! I actually remember seeing that. Oh well, I'm still very happy with my puzzle :) And here are the mechanism pictures for everyone.

It look very nice, Scott. Out of curiosity how did you make the center parts. When I made mine I made one of the parts have a counterbore hole thru with the counterbore on the outside. On the other center it was just a threaded hole on the inside. How did you make yours?

Precisely the same way. The CAD drawing I posted is slightly out of date. I made a new male center piece before 3D printing. And my female center piece is just a tapped hole.

I feel obligated to post this.

It's Jin's sketch that is who knows how old.

Where are all these cuboids coming from? Oh yea, they only have 6 cubies so I can whip them up in about 20 minutes. :) The two black tiled ones are for me and my girlfriend. and the white one has already been sold to someone on the waiting list.

3D printing is the future, unquestionably. Quality of the puzzle will eventually be taken out of the hands of the manual builder, since it will never truly meet or exceed a machine. The skill remaining will be how well the builder can make a decent mold and cast a resin piece. Eventually that will be replaced too when 3D printing improves. In the end, it will boil down to how imaginatively one can design a mechanism in a CAD program.

I can't take any credit for the 1x2x3. I thought the idea was so trivial that anybody could have done it. But I just might have been the first joe-shmoe to commit the idea to paper. No, probably not even that.

For now I'll stick to the strictly manual method. Call me a 20th century throwback. :)
