SpaceCubes (Skill Puzzle)

Update: 5/6/2016
Based on your machines print quality I have made two models. They are about the same except the loose model is designed for machines that print thicker parts. If you machine is dialed in perfectly use the Tight model. Due to the design of the interlocking parts, they need to fit together snuggly, but not too tight.

Great Skill Puzzle toy. This puzzle first came out in the 80's called Chain reaction and is now being manufacturing again! For easier printing the links ha
