Small but devious!

This 2/3 scale version of The Barrel Cooper's Puzzle Box includes all the tricks of the original with a few more twists!

Introduction https://youtu.be/URUGXzpI2-I

New Stuff!

• Removes the "snap to position" spots. Solvers will need to work harder to logic out the correct rotation points. The puzzle still hints at these with visual indicators for those looking closely.
• Removing the cork now requires an additional step.
• Fewer parts to print!
• Less hardware to assemble!

Hardware

The mini version of this puzzle uses less hardware than the original! It can also support a wider range of bolt sizes.

Requered

One of the following bolt options:

M3 x 50mm Bolt & M3 locknut M4 x 50mm Bolt & M4 locknut M5 x 50mm Bolt & M5 locknut

You can also try bolts as short as 40mm, but that does not leave much room for the locknut.

Recommended
