Soma Cube Puzzle with Base and Cage

Soma Cube Puzzle

Fit all seven pieces into a 3 x 3 x 3 cube.  Or try to make many other shapes and designs.

What is different about this version of the Soma Cube than my previous version?

Each cube is centered on a 15 mm grid, but is reduced by a 0.1 mm ‘play’ on each edge.  This allows pieces to easily fit together without binding.  See my blog post for more details.

Why are there two base and cage parts?
What are the holes on the base and cage for?

There are two versions of the base and cage parts.  The two parts with the small holes are designed to accept very small 2 mm diameter by 1 mm thick magnets.  They are sized so that a single magnet can be forced in the hole.  I use a small rubber tipped hammer to secure them in place.  A tiny amount of super glue can also be used.

Printing Notes

All parts print without supports.  I typically use 10% infill and both 4 top and bottom layers for consistency.  Print the cage upside down (as it appears in the .stl file) as it only needs minimal bridging.

More cube puzzles will be coming soon.  Follow me here or watch my blog for updates.
