3D Prints of Portal’s Companion Cube are a dime a dozen, usually made as a paper weight (heh) or sometimes as something slightly more interesting involving electronics, as is the case today with this case for a GoPro.

Maker David Palma is the one behind this project, designing it to work with the Hero5 Session.

Palma tells us that the modelling work for this print was done in AutoCAD over the period of just one hour.

Printing took slightly longer at four hours, the process of which you can see in a short timelapse video that we’ve turned into a gif. Timelapses for 3D prints seem to be popular right now as we also saw one made for Barad-dûr from Lord of the Rings.

With the printed pieces fitted to the GoPro the entire assembly measures in at around 48 millimetres squared.

No filler or sanding was done here, with just glue used to stick the various sides of the cube together. A paint job using acrylics filled in the simpler colour scheme and the project was finished, the results of which you can see in the gallery below.

As you can see one of the sides of the cube has a cutout to access the buttons.

Those looking to make their own GoPro / Portal crossover can find the files to do so available for free over on Thingiverse.

If you’re looking for a 3D printed Companion Cube that does a bit more than hold down paper but doesn’t fit a GoPro, see our feature on a version with motion-activated lighting.
