Hi,
I'm new here so I don't know whether this is of any interest to you guys, but I thought I'd give it a go.
I've been designing interlocking cube puzzles for about 7 years now. I used to make them out of wood and then LiveCube blocks, but now I specialise in 3D printing my designs at Shapeways.
I mostly print in the White, Strong and Flexible material (nylon) which makes for good strong pieces at relatively low cost. I have also experimented with printing some of my designs in steel, mostly successfully. The cost is higher but the effect is very impressive.
I am just starting a new range of designs based on a hollow lattice with a cubic outline, instead of solid unit cubes. This means I can print larger puzzles without the cost being prohibitively expensive.
My latest design called
Quaturnery Qube costs just $30 from Shapeways.


Most of my designs have solutions on YouTube - just search for
microcubology.
Hope you find something interesting there. Happy puzzling.
