Yes, another Gift box!
Full disclosure: I've never actually played any of the Portal games. I know people who have played them and loved them, but I've never actually played them myself. But even I know about the Companion Cube; originally created by the insane computer GLaDOS to test how the player would respond to something they cared about being incinerated. I think Cake was involved too somehow, but I'm not sure where that fits in...
I decided with this box to cut out the whole 'incineration' thing and just see how people would react to someone they care about being given a nice gift in the Companion Cube instead! It's big enough inside for some earrings, a set of keys for a new car or house, or that special ring for that special person (and you can print the cube with either a single or double ring holder, with a foam rubber lining in order to hold the ring/s for you. Or you can just have it bare, for any lining you want to put in it!
The print should be fairly straightforward, you'll need of course to find the foam rubber for the ring holder should you decide to use it. If you don't have a 3D printer but you'd really like one of these please send me a DM and we can arrange for me to produce one for you, or check out my Numonday store:
