Compatible with my tunnel baseplate, this allows you to route the charging cable down through your baseplate, without needing to manage it through/around other grid modules nearby.

v1 of this model was a 2x1 footprint, which may work, but with a watch sat on it may interfere with adjacent modules.

Testeed with standard Apple charging puck.
