The blaster needs to be supplied with compressed nitrogen gas or dry air with a pressure of roughly 80 psi. The air flow is split into a high-pressure and low-pressure (20-25psi) line with a secondary gas regulator. A trigger mechanism controls the high-pressure line. Fine ground dry ice is loaded into the top reservoir of the blaster. The trigger mechanism requires some non-3D printed items listed below.
