Valve Opens Steam Controller Hardware for Modders
Valve has released a complete set of CAD files for its new Steam Controller and Puck, available under a Creative Commons (CC) license. The release includes .STP and .STL files alongside engineering diagrams, giving hardware enthusiasts and modders everything they need to design custom accessories.
What Modders Can Build
The files cover the external shell (surface topology) of both devices. Engineering diagrams also highlight areas that must remain uncovered to preserve signal strength and operational integrity. With this data, modders can create skins, charging stands, grip extenders, smartphone mounts, and more.
Valve's Open-Hardware Tradition
This release continues a pattern Valve has maintained for years. The company has previously released CAD files for the Steam Deck, the Valve Index VR headset, and even the original Steam Controller over a decade ago. While expected, the community has welcomed the release warmly.
Commercial Use Pathway Available
The CC license restricts use to non-commercial, attribution, and share-alike terms by default. However, commercial entities interested in creating official accessories can contact Valve directly to discuss licensing arrangements, signaling that Valve is open to expanding the Steam Controller hardware accessory ecosystem.
