Adjustable Paper Cutter

Custom razor blade

This was made for a engineering competition where they have to cut strips of paper in a timely manner.

I cut up strips of Lexan and then roughed them out into roughly the same sized pieces. I then chucked them up in a mill and faced 2 sides to be equal so you can rotate them 90 degrees to get the same hole pattern in all of them. I then just used the x and y coordinates to stack drill them to where the screws would capture the razor blades. Washers could be inserted in between the layers to get whatever width strips above .25 inches. I then took this concept to make 3d prints, mostly to prove that a 3d printer can make something much much quicker and with less equipment.
