K1 Max Small Tool Tray works with the K1 Max Tool Tray I published. This unit mounts around the right front foot of K1 Max printer. The tray holds some additional items needed that may be needed for 3d printing. The K1 Max Small Tool Tray must be pulled out after pulling the K1 Max Tool Tray I published. Please download both models for ultimate storage under the Creality K1 Max.
