I just tried to print up the 1x2x3 Rubik’s cube puzzle from TomZ.  I really like the idea of it.

Unfortunately, it’s just not working for me.  I had to rotate all of the STL’s 90 degrees to make them printable.  Once most of the parts were printed I discovered it’s not going to fit together.  The swivelly bits on “Part 1” are too large to rotate freely inside the center cubes.  If the grooves in “Part 2” were much larger it wouldn’t fit inside the part.

At this point, it’s probably easier to start building the entire puzzle from scratch.  Here’s what I’m thinking:

1. Make the swivelly bits on Part 1 smaller
2. Make the grooves in Part 2 slightly larger
3. Make a notch in Part 2 and Part 3 so that it can be put together with an M3x16 nut and bolt instead of a plastic pin
