Matzo Slicer

My son has a homework task that he had to do during the Passover holiday. He had to invent something useful, so we invented this Matzo Slicer to overcome the problem that it is very hard to cut a Matzo to two equal slices. Since the size of the Matzo can vary, I made it a little bigger and added small piece that you can print that let you calibrate the slicer to the correct size. You can print more than one such a piece.
