## Cruiser (STC #167) ### A tray-packing puzzle by Stewart Coffin Fit all four pieces into the rectangular opening. This puzzle is one of a [series of tray-packing puzzles](https://www.thingiverse.com/asiegel/collections/stewart-coffin-tray-packing-puzzles). It's a delightful design, seemingly simple yet surprisingly tricky. Coffin wrote of this puzzle: "This little gem is a sequel to Few Tile #133 and a top favorite among my flat tray puzzles because of its deceptive simplicity. Fit the two trapezoids and two triangles into the rectangular tray. Mary and I would take one along on our various travels to entertain our companions, hence the name. Seldom could any of them solve it." There are three STL files: the pieces; the tray; and an optional lid. The tray includes an extra space for one of the pieces, for easy storage while the puzzle is in its unsolved state. It's modeled using [puzzlecad](https://www.thingiverse.com/thing:3198014), and I have included the .scad file in case you want to remix it. You will need puzzlecad version 1.3 or later. ### About the Designer Stewart Coffin is perhaps the most influential designer of interlocking mechanical puzzles, having produced a wide range of ingenious designs of various shapes and complexity.
