Valve Releases Steam Controller CAD Files Under Creative Commons License

With therather excellent Steam Controllernow on its way tothe lucky fewthat managed to order one, Valve has released a full set of CAD files for their new hardware. The idea is to let enterprising modders create their own Steam Controller add-ons, like skins, charging stands, grip extenders or smartphone mounts.
The Valve release includes files for the external shell (“surface topology”) of the Controller and Puck, with a .STP, .STL and engineering diagram of each device, with the latter showing areas that must remain uncovered to let the device maintain its signal strength and otherwise function as designed.
Valve has previously released CAD files for its Steam Deck handheld, Valve Index VR suite and even the original Steam Controller a decade ago, so this release is welcomed but not unexpected.
The release is under a fairly restrictiveCreative Commons licensewhich allows for non-commercial use and requires attribution and sharing of designs back to the community. However, the license also suggests that commercial entities interested in making accessories for the Steam Controller or its Puck can contact Valve directly to discuss terms.
What is your ultimate Steam Controller or Steam Controller Puck accessory? Let us know in the comments below. For me, it would definitely be a smartphone clip - playing through something relatively low-stakes like Forza Horizon 6 via Moonlight game streaming on a phone would be slick.
