Valve has published the exterior CAD files for its Steam Machine, letting anyone download the 3D blueprints and design custom parts for the console. The files went live on 29 July 2026 at gitlab.steamos.cloud, according to Eurogamer.

The release carries a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International licence. In plain terms: you can share, remix and adapt the files freely, but you cannot sell anything you make from them. Any wrapper, skin or front plate produced using the official designs is legally barred from commercial sale.

Valve engineer Pierre-Loup Griffais flagged one catch for tinkerers. Any damage caused by modifications will not be covered by the Steam Machine's warranty, he warned. The CAD files are primarily intended to help users create custom front plates for the device — the swappable panel on the console's exterior — but Valve expects people to go further.

The news lands amid a growing market for unauthorised Steam Machine accessories. In June 2026, accessory maker dbrand cancelled a planned Portal-inspired Companion Cube wrap for the Steam Machine because it had not been licensed from Valve. At the time of reporting, knockoff versions of the console itself were already emerging on the market.

The Steam Machine is Valve's living-room hardware, which the company's Steam store page describes as having "over six times the horsepower of Steam Deck" and capable of running AAA titles. Valve first unveiled the device alongside two other products — the Steam Controller and the Steam Frame — in a December 2025 announcement, stating all three are optimised for Steam. The company has said the Steam Machine's reservation queue will be cleared by the end of 2026, and the device recently gained support for AMD FSR 4.1, an upscaling technology that renders games at a lower resolution and reconstructs them to a higher one for better performance (VideoCardz).

Digital Foundry was the first outlet to report on the CAD file release.

For owners, the files open a door that accessory companies have been knocking on for months — the chance to personalise the machine's exterior without waiting for Valve to commission an official skin line. The non-commercial licence, though, draws a clear line: make it for yourself, share it freely, but do not put it on a shelf with a price tag.
