Install the unused Snapmaker 2 toolheads on your Z-axis. The SnapMaker 2 A350 I'm using can accommodate up to two toolheads, so all of them are within easy reach. At the same time, you can easily store the 3D printing nozzles without having to remove the consumables, which is both convenient and practical.

Use the two M4 screws provided to fix it on the Z axis.
