Ill-fated Companion Cube case for Steam Machine returns as a 3D-printed effort — and it's not the only striking DIY project around Valve's gaming PC

• Someone has made a custom version of the Companion Cube case for the Steam Machine
• This DIY effort is on Printables, and can be 3D-printed for those with the hardware and necessary skills
• There are a growing number of custom projects around the Steam Machine, from faceplates through to full-on alternative takes on the gaming PC

Remember the ill-fated Companion Cube case for the Steam Machine? It had the plug pulled on it by Valve a few weeks ago, after maker Dbrand failed to get official permission to make its hard-shell case for the gaming PC, but now the concept has returned, in DIY form.

Tom's Hardware reports that a user on Printables, Jaron, has provided files that allow you to 3D-print your own version of the Dbrand Companion Cube (as flagged on X). You can print the pieces, and a full set of assembly instructions (including smart video illustrations) and extra necessary parts (screws and so forth) are supplied.

As made clear on X, this is a fan-made creation implemented "from scratch" and it's based on images of Dbrand's Companion Cube. Whether it'll attract the attention of Dbrand's own lawyers, well, we'll just have to see, but you'd imagine that some leeway might be granted here given the situation and what happened with Valve.

The creator makes it clear that the case isn't an official product, is nothing to do with Valve, and that it doesn't use "any official assets from any game".

An additional caveat is that Jaron notes: "I have not done any extensive thermal tests but no airflow or venting is blocked, and the additional vent provided by the front face plate aperture logo can help provide a little extra airflow. So I don't believe there will be any cooling issues caused by this case."

My main concerns about the original Dbrand Companion Cube were bound up in cooling issues — especially on warm days, in confined spaces like a TV cabinet — and that remains true with this creation.

Still, if you were disappointed that Dbrand's case was cancelled, and you have a 3D printer and want to have a crack at making your own — and you're pretty decent with a soldering iron — you can now do just that.

Other Steam Machine companions

Since the Steam Machine came out, there's inevitably been a lot of interest around the device, despite the high price. So, as well as this clone of the abandoned Companion Cube case, what else is out there in terms of Steam Machine customization?

New faceplates (front panels) are popular, and a much easier project than the above case, such as this example on Reddit (see the image above). I really like the slat effort here, and I can see why it's gone down very well with other Redditors (although I'm not so keen on the blue one).

What's also quite common is the number of custom small form-factor (SFF) PCs which are DIY takes on the Steam Machine, generally featuring beefier components (and at the same time, inevitably being larger than Valve's PC). 'The Orange Box' as shared on Reddit is a particularly smart example of one such effort with a strong Valve theme, built in a SilverStone SG05BB-Lite case. It has a Ryzen 7 5800X processor inside and an RX 9060 XT graphics card to give this considerably more pep than Valve's gaming PC.

There are other custom SFF PCs on Printables and this one from 3DCatt, which looks like a sized-up Steam Machine, has very similar aesthetics to fit your living room nicely, and a finished version someone has completed went very well indeed by all accounts.

Of course, there are issues around these alternatives to the Steam Machine as I explored in detail recently, and downsides to these custom SFF builds – albeit definite positives too, better performance being the main one. A PC that looks as good as The Orange Box doesn't hurt, either, and I'm sure we'll see more of these kind of SFF spins on the Steam Machine going forward.
