This is the design file for the pentiamond puzzle pieces item in my showroom. From a P2 (15.75" x 15.75") sheet it makes 75 puzzle pieces: 18 of each of the 4 pentiamond shapes, plus 3 extras. One of the photos shows the design; others show the puzzle pieces made from this design and a couple of the shapes you can make from them.
As of Sept 23 2012, Ponoko will make this design from 3 mm acrylic for:
$10.99 (material) + $14.67 (laser-cutting) + approx. $11 (shipping by UPS ground to lower 48 U.S. states).
