Valve won’t necessarily sell any of those extra panels, but says it’ll release the CAD files so you can design and 3D print your own. “I’m sure someone will make a [Portal] Companion Cube out of this, but we did not,” Valve engineer Steve Cardinali tells us when we ask. Below the panel, Valve also has a customizable RGB light bar that it plans to turn into a progress indicator for downloads and updates.
