For Mechanical Design we had to make the Snap. We determined that the best way to snap the parts together was to use a screwdriver to bend the flexure both ways. Then You put one side in and work on the other side. First we laid out the pieces and labeled where they went such as front left. We put the four sides together then put them on the base. When we put them on the base we had to work on one side at a time then after getting all sides partially in we had to push them all in fully at the same time.
