Valve releases Steam Controller and Puck CAD files for modders and accessory makers
Valve has released CAD files for the new Steam Controller and Steam Controller Puck. The files cover the external shell surface topology and are available under a Creative Commons license.
The package includes STP and STL models for both devices. Valve also added engineering drawings with critical features and keep-out areas. These files give modders and accessory makers reference data for shells, mounts, docks, stands and other custom parts.
Steam Controller and Puck CAD files now available!
Greetings! We have exciting news to share for those of you who want to hack, mod, or design accessories for the Steam Controller and Puck.
Today we’re making the CAD files for the external shell (surface topology) of Steam Controller and Puck available for download under a Creative Commons license. This includes an STP model of each, an STL model of each, and an engineering drawing with critical features/keep outs for each.
You can find the files here. We can’t wait to see what you all create!
This is not the first time Valve has opened its hardware designs to the community. The company released CAD geometry for the original Steam Controller in 2016, CAD files for Valve Index headset, controllers and base stations in 2019, and external shell files for Steam Deck in 2022.
Steam Machine will also be mod friendly design, CAD file release very likely
Steam Machine has a removable front panel and Valve previously said it would release CAD files so users could design and 3D print their own panels. As we reported earlier, JSAUX has already been preparing custom Steam Machine panels , while dbrand teased a Companion Cube-style skin.
CAD files are useful beyond hobby 3D printing. They allow accessory brands to check dimensions, clearances and surface geometry without reverse engineering the hardware. For Valve systems, this can help companies explore custom panels, mounts, grips, covers and other hardware add-ons once the devices are available. Basically free input from crafty people and perhaps some suggestions for the 2030-era Controller.
Speaking of the controller, the gamepad sold much quicker than Valve anticipated, but they are working on solving that issue:
Steam Controller ran out faster than we anticipated, and we hate that not everyone who wanted one was able to get it. We’re working on getting more in stock and will have an update on expected timeline soon.
