Pentomino Puzzle

thingiverse

The objective of this puzzle is to fit all the components inside a base measuring 6 by 10 units. There are 12 distinct pieces, each consisting of 5 square units. You can rotate and flip the pieces as needed. A total of 2339 solutions exist for this puzzle; I placed the number on the base so I wouldn't forget it. The lid has a solution that allows all the pieces to be fitted together, enabling you to place the lid on seamlessly. To print, use the file containing all the pieces or print each one individually if you prefer a more colorful outcome. You can also attempt to fit them within a 5 by 12 area (1010 solutions), a 4 by 15 area (368 solutions), or a 3 by 20 area (2 solutions). Update 3/24/20: I have updated the lid to make it easier to print. "Lid v2.stl" is the new version, and the old version remains available.
