This is the companion cube from the Valve game Portal.

I modified this model to help align the different faces together.

Portal is one of my favorite games which is why i wanted to make this.

The cube is split up into the individual faces to improve the print quality.

INSTRUCTIONS:

Print the build plate twice to get all six sides of the cube.

To glue all the sides together I used hot glue, but you can use whatever glue you think works best.

I sanded and of the individual faces before gluing them together, i also sanded the connecting faces, to make them fit together better. I filled the remaining gaps with wood filler, which I then sanded the edges. I primed the model, then gave it an under coat with a metallic paint before gave the model the base coat, i later sanded off the base coat to reveal the metallic paint, to create chipped paint effect. I gave the cube a coat with dark brown watercolour paints which i wiped off with a damp cloth to create a dirt effect.

This was based on this model:
