Designed to hold a set of three tools—water jet pliers, a spatula, and a trimming knife—the storage unit is mounted on the side of the machine for easy access. It occupies the No. 1 material bay; simply remove the No. 1 rotary axis, replace it with an M3×8 screw (preferably a countersunk screw—countersink holes have already been pre‑drilled in the model), and secure it in place.
