This is a holder for the subminimal nanofoamer that allows it to be used almost like a steam wand. It requires the wall mount and a small piece of foam to prevent moving. It is compatible with nanofoamer v1, v2, and lithium. Stick the foam to the back of the subminimal wall mount, then stick the wall mount to plate 1/plate and screw.The image shows the support rod that needs to be cut off.
