SpaceCubes (Skill Puzzle)

Based on your printer's quality, I have designed two models that are similar except the loose model is suitable for machines that produce thicker parts. If your machine is perfectly calibrated, use the tight model. Due to the interlocking design of the parts, they need to fit together snugly but not too tightly. This puzzle has a great skill level and is a fantastic toy. It first came out in the 80's under the name Chain reaction and is now being manufactured again! To make printing easier, the links have been cut in half and need to be glued together. Please print and provide feedback on this design, which is still a work in progress.
