Small and tiny pentomino sets

You can find a lot of printable pentomino sets. I just felt like making my own design and keeping it as small as I could get it. I could probably print smaller than the 3mm grid pentominoes, but it is about the limits of usability for me. Maybe next time I'll add some printable tweezers. :)

I scaled up to 4mm to make a more reasonable set. Because my design shows the split into squares, it was originally hard to see the individual pentominoes in a solution. To fix this, I added markings that cut through the whole pentomino and show the “spine” of the shape. You can remove them by going to the original design in Tinkercad 3mm or 4mm.

This model contains 6x10, 5x12, 4x15, and 3x20 boxes, and the 12 pieces can be packed into each of them.

The solutions shown in the photos are taken directly from the Wikipedia page. There are many other solutions to look for. I have added a lid for the 6x10 box so the set can be carried conveniently.
