VACUUM FORMER
A vacuum former is a special piece a machinery found in a workshop. It is used to shape plastic. We will be using it to make a cover for your electronics project. The plastic will be molded around a piece of wood the exact size of your circuit board. It will fit over the circuit board and some tape can be used to secure it in place.
