Here’s something that I did a while back that I finally gotten around to finishing. Fans of the game Portal and Portal 2 will recognize this as the iconic Companion Cube that you carry around with you for a large part of the game. I designed and printed this a while back when I was trying to improve my skills with Autodesk Inventor and I’m pretty happy with the final design.

Being a modular design, the nine pieces minimizes the amount of materials and time required to print all the parts. The print itself is made of ABS plastic and the paint consists of a few layers of car paint primer and was painted by hand using acrylic paint.
