A community-led project has introduced a DIY solution for PC gaming enthusiasts seeking to customize their hardware, following the abrupt cancellation of a similar commercial product. The initiative allows users to transform their Steam Deck or other compatible hardware into a custom “Companion Cube” aesthetic, inspired by the iconic design from the Valve-developed Portal franchise. This development follows a legal intervention that halted the retail sale of a third-party accessory kit.
The Shift from Commercial Product to Open-Source Design
The transition began after the accessory manufacturer dbrand discontinued its “Portal-themed” case for the Steam Deck. According to public statements from the company, the decision to stop production and sales of the accessory was a direct result of communication from Valve Corporation regarding intellectual property rights. While dbrand did not disclose the specific legal documents, the company confirmed in official social media updates that it ceased all fulfillment of the product following contact from the game developer.
In response to the sudden removal of the product from the market, members of the enthusiast community began developing their own methods to achieve a similar aesthetic. Several creators have since released 3D-printable files and assembly guides, allowing individuals with access to a 3D printer to fabricate their own custom enclosures. These DIY kits are distributed freely online, enabling users to modify their hardware without relying on commercial entities that may be subject to trademark enforcement.
Understanding Intellectual Property in Gaming Hardware
The situation highlights the complex intersection of fan-made modifications and corporate intellectual property (IP) enforcement. Valve Corporation, which owns both the Steam platform and the Portal series, maintains strict control over its visual assets and branding.
How the DIY Community Adapts
The current DIY approach relies on the accessibility of consumer-grade 3D printers and open-source CAD software.

The Future of Custom Hardware Modifications
For those currently working on their own builds, sharing progress on enthusiast forums remains the primary way to contribute to the evolving documentation of the project.
