This is a recreation of a puzzle that Juno, when he was in his late teens, brought to the hospital during visits to his hospitalized grandfather to help relieve his boredom. Just like the puzzle being auctioned this time, it was made using leftover materials from a burr puzzle he had built. Juno later learned from his grandfather that the puzzle had become quite popular among the elderly patients in the ward.

This puzzle has three solutions. Even those who are not accustomed to mechanical puzzles will likely find it solvable if they take enough time.
