I made this puzzle from 30×30 mm wooden cubes. I cut them from a 30×30 mm ready stock with my hand miter saw. For ornaments my old technical drawing stencils was very useful. I painted them with color gel pens and applied very thin lacquer. I made also some other versions,
Example on the left has stand and I drilled each cube center. But this version isn’t good to play, second version is made from plastic school cubes. I drilled spots on faces. very easy to make.
This puzzle has also 5 and 6 cube variations produced with different commercial names. Five cube version has five color(or shape) and six cube version has six color (or shape). You can find all information for 5 and 6 cube versions and method for solving them from here.
You can make ornaments on each face also by wood burning. You can see some nice vintage examples from J.A Storer page.
