Valve publishes Steam Controller and Puck CAD files to help modders design accessories under a Creative Commons license

Valve released CAD files for the new Steam Controller and its Puck, including shell topology, STL/STP files, and engineering diagrams showing areas that should not be covered. The files are available under a Creative Commons license allowing non-commercial use with attribution and shared derivatives, while commercial accessory makers can contact Valve for separate terms.

The move continues Valve’s pattern of supporting hardware tinkering around devices like Steam Deck and Valve Index, encouraging a community accessory ecosystem before the controller reaches many users. By giving modders official dimensions while reserving commercial licensing, Valve can foster open hardware experimentation without fully giving up control over paid accessory markets.
