Valve releases CAD design files for its new Steam Controller and accompanying Puck under a Creative Commons license, according to reports referencing Digital Foundry. The published materials are intended to let modders build accessories for the devices, including items such as skins, charging stands, grip extenders, and smartphone mounts. The release includes files covering the controllers’ and puck’s external shell geometry, described as “surface topology,” provided in formats such as .STP and .STL, along with engineering diagrams for each device. Those diagrams indicate areas that must remain uncovered to preserve the devices’ signal strength and functional requirements.
Multiple outlets note that this is part of Valve’s broader pattern of making hardware design files available to the community. Valve has previously released CAD files for other products, including the Steam Deck handheld, the Valve Index VR suite, and earlier versions of the Steam Controller. The Creative Commons terms are described as non-commercial and attribution- and share-back oriented, while also indicating that commercial parties can contact Valve to discuss terms for accessory development.
