Barrel Axis Cube

thingiverse

This brain-twister is a compact 3x3x3 Axis Cube cleverly disguised as a barrel. You have the option of printing the included core or substituting it with an extra one you already have on hand. This puzzle doesn't employ springs, so instead you'll need to secure it with six M3 screws that are 12-16mm in length.
