3D printing enthusiast resurrects cancelled dbrand Steam Machine Companion Cube as DIY project — project shelved due to copyright can now be made and assembled at home
Mere weeks after dbrand announced it would have to shelve its Steam Machine Companion Cube because it didn’t get permission to use Valve‘s intellectual property, a 3D printing enthusiast has created a DIY version that you can make for yourself at home. Printables user Jaron’s Steam Machine Companion Cube Case is “An unofficial Portal Companion cube case for your Steam Machine” that you can create using a single-extruder printer, if you have the right model.
According to a user post on X, the fan-made tribute to the dbrand project was made “from scratch,” and is based entirely on images of dbrand’s design. Ironically, whether that will incur any copyright wrath from dbrand itself remains to be seen.

As you can see, the project looks exactly like dbrand’s companion cube. According to the Printables listing, it can be printed using a single-extruder printer as long as it lets you pause at specific layers to swap filament for other colors. Jaron says a slicer is required to get the multi-color look for the panels, but otherwise provides an extensive parts list of screws, inserts, and magnets you can acquire from Amazon to piece the project together. You will, of course, also need a Steam Machine for the full effect, as well as a soldering iron, tweezers, and a couple of screwdrivers. Helpfully, they even list the specific Sunlu and Overture filaments used to get the look.
At first glance, this is definitely not a beginner 3D printing project, but Jaron has provided extensive assembly instructions as well as multiple YouTube videos to detail the assembly process. As you might expect, popping a 3D-printed shell on your Steam Machine might impact thermals. Jaron says that they have not done any extensive thermal testing of the design, but has ensured that no airflow or vents are blocked. In fact, the additional vent in the faceplate may even aid cooling.
dbrand unveiled its Companion Cube on November 12, the day of the Steam Machine’s announcement. Following extensive interest, the company says it poured thousands of hours into industrial design and injection molding, as well as promoting the Companion Cube. Unfortunately, it forgot to ask Valve for permission. “They stated that the Companion Cube is Valve intellectual property, for which dbrand does not have a license,” the company admitted in a statement last month. Despite appeals, the company in the end gave up and shelved the project.
Valve’s Steam Machine is the company’s somewhat beleaguered in-home console alternative, which finally launched last month. The diminutive desktop gaming PC is a lot pricier than Valve had anticipated, owing to the AI pricing squeeze on RAM and SSD parts. As such, at $1,049, it’s decidedly more expensive than console alternatives, somewhat limiting its appeal. With a semi-custom AMD Zen 4 six-core chip, RDNA3 graphics, 16GB of DDR5, and up to 2TB SSD capacity, it’s pretty good value when compared to equivalent PC hardware.
If you have got your hands on one and would like a version of dbrand’s Companion Cube to match, this enthusiast 3D-printed project — which Jaron says is not affiliated with Valve or Steam, nor features any official assets from any game — could be a fun way to spend a weekend.
