Four Sleazy Pieces

Tray-packing puzzle by Stewart Coffin (STC #169-A)

Fit all four pieces into the rectangular opening.

Four Sleazy Pieces is one of a series of tray-packing puzzles by Stewart Coffin. It seems impossible at first, but it isn't... if it seems like the pieces just won't fit the way you expect, or the tray size is just a little bit off... don't worry! There's nothing wrong with the model or your printer. Keep trying. (The other puzzles in the series can be found on the Stewart Coffin Puzzles collection page.)

This is perhaps one of Coffin's lesser-known puzzles in this genre. If you're unfamiliar with his tray-packing puzzles, I'd recommend starting with one of the others first; the linked collection page has some recommendations.

Printing Instructions

Print one copy each of coffin.four-sleazy-pieces.pieces.stl and coffin.four-sleazy-pieces.tray.stl. Optionally, you may print coffin.four-sleazy-pieces.lid.stl as well, which is a lid that fits over the tray for easy storage.

The Printable Puzzle Project

The Printable Puzzle Project aims to make available high-quality open-source models of many puzzle designs. All of our models are posted with the generous permission of their designers and are licensed for non-commercial use only. Anyone may print copies for their own personal use, but selling or otherwise monetizing them is not permitted, and puzzle designers retain all rights as copyright holders of their work.

Our puzzles are modeled using the open-source puzzlecad library. The .scad file is included with this model in case you want to modify any of its design parameters; more information on how to do this can be found in the PPP Puzzle Modeling tutorial.
