12-Piece Separation

thingiverse

Stewart Coffin's classic design has one of its most iconic puzzles; in fact, getting it apart is almost a breeze compared to putting it back together again! Duplicate the standard piece ten times and create an extra copy each of the key piece and its matching partner.\r\n\r\nThree distinct surface offset size options are available. Start with the minus-75 files first; if they don't fit snugly, try switching to minus-50, but if they're too tight, opt for minus-100 instead.
