Valve has released the CAD files for their Steam Controller so anyone can get creative with the hardware and start making modifications.
Valve say they are “eager” to see what the community can come up with when it comes to modifications, although if anyone wants to sell their creations, they’re going to have to talk to Valve first.
The files are being made available under Creative Commons licensing and include the geometry of all externally visible parts. The files can be grabbed in a zip which is available on the Steam controller community page on Steam.
The zip archive released contains “several eDrawings viewer files: from Creo Express and native Modeling, to neutral exchange and 3D print files – for compatibility with a wide variety of your design tools.”
Perhaps someone will come up with a way make it look less owl-like.
