# Valve releases Steam Controller CAD files under Creative Commons license

With the new Steam Controller now shipping to the lucky few who managed to order one, Valve has released a full set of CAD files for the new hardware so modders can design their own accessories — skins, charging stands, grip extenders, smartphone mounts.

The release covers the external shell ("surface topology") of the Steam Controller and the Puck. Each device gets `.STP` and `.STL` files plus an engineering diagram. The diagrams mark areas that must remain uncovered for the device to maintain signal strength and otherwise function as designed.

Valve has done this before — CAD files for the Steam Deck, the Valve Index VR suite, and the original Steam Controller a decade ago. So the release is welcomed but not unexpected.
