Weighted Companion Cube
thingiverse
Introduced in Portal and continuing its presence in Portal 2, the Weighted Companion Cube is similar to the Weighted Storage Cube but with a different design. Designed to make test subjects feel attached, it functions like a Weighted Storage Cube but cannot speak or threaten. The model of this cube is from Portal's Orange Box and copyright belongs to Valve Corporation. Many on Thingiverse who shared Companion Cube models didn't do a good job; however, the most accurate printable version is now available for download at thingiverse.com/thing:33140. Remember not to harm your only friend!
