I needed a board that I could adjust in size based on the puzzle we do in my house (55-2000 pieces). It can also be broken down and stored more easily than the giant wooden boards. My printer is smaller, but they can be scaled larger or smaller as well!

UPDATE 3.0! I think after some additional tweaking, I finally got it right! Feel free to scale these larger to print less pieces! You can also scale them thinner to use less filament before slicing!
