Valve releases Steam Controller CAD files under Creative Commons license

Valve has released CAD files for the Steam Controller and its Puck accessory under a Creative Commons license to enable modders to create custom add-ons like skins, charging stands, and smartphone mounts. The files include external shell designs in multiple formats (.STP, .STL) and engineering diagrams showing which areas must remain uncovered for proper functionality. The license permits non-commercial use with attribution and requires designs to be shared with the community, though commercial entities can contact Valve to negotiate different terms.
