Step 3 Cut the PE or styrofoam

We need to cut 3 pieces of PE foam or styrofoam. PE foam is often used to protect computer or measurment or other sensitive equipment during transport it should be easy to get when asking around if you don't have it yourself. Styrofoam is even easier to get, but a little harder to work on. Styrofoam can be bought at DIY stores as a standard isolation material for houses.

We need to cut two 12x12 centimeter squares that are 3.5cm thick. A 3.5x3.5cm hole must be made in the middle of the squares. We also need to cut a 46cm long beam that is 3.5x3.5cm square. The beam should fit snugly in the 2 squares we've already made.
