First you print it, then you solve it. The first photo shows the snake cube solved, the second photo shows the snake cube as it comes off the 3D printer. Fold the printed version into the final version, no strings, wires, motors, screws, glue or cranks, just frustration. However, as the photos show, it can be folded into a cube.
This snake cube puzzle prints fully assembled and ready to solve. To increase the difficulty, I paused the printer at 10mm and changed from white to black filament.
I saw this video http://woodgears.ca/puzzles/snake_cube.html and this thing http://www.thingiverse.com/thing:10486, but both used string to hold the cubes together. I was looking to build a fully assembled ready to solve snake cube puzzle and, well, this is it. Hope you print and solve it.
Designed using Sketchup 8 and printed in PLA on a Makerbot Replicator 2 using Makerware 18.104.22.168.
Print this thing then figure out how to fold it into a cube.
I learn then smile, so that others may smile then learn.
