I have tweaked my laser cutting patterns a bit and resubmitted my Pentimo design to Ponoko so I can order a complete set. I am holding out for now though: At about $3.50 each for thin wood dominoes, that makes a complete set (51) a bit rich for me to spring for on a whim. I will need to sweet talk myself into it.
Black Plastic Pentimo (render)
I have also worked out a similar set in a thicker 9mm black plastic at just over $5 each. Even more interesting, to my sense of aesthetic at least, are the sets I designed that are etched on a 4.5mm plastic, with decorative backs and pipped faces, so they can be bonded together to create Pentimoes with decorative backs that are about 9mm thick too. These also run just over $5 for each completed domino, but require assembly.
