This is a mount for the FastSnail Charger Dock for Nintendo Switch Joycon controllers for the Honeycomb Storage Wall (HSW). The charger can be found here or at the link below.

I recommend printing this with the top side down (HSW Connectors Up). Supports are recommended for the main side opening only.
