Introduction: Weighted Companion Cube

By popular demand I made the Weighted Companion Cube from Portal.

Step 1: Materials and Tools


some sort of hardenable or bakeable clay
red paint
white paint
black paint
Silver paint (not necessary, I think it looks better than white though.)


cutting knife or blade

Step 2: Cube Beginning

Make a cube out of the clay.
Use the blade to make a plus on each side.

Step 3: Cube Edges

Make 8 small equilateral triangles.
Push the triangles onto each corner and shape them.

Make 8 small rectangles.
Push them onto the edges between the triangles.

Make 6 small balls of clay.
Squish them and push one into the center of each side of the cube.

Step 4: Paint

Bake the cube if it is a baking clay, let it dry if it is a hardening clay.

If you want the edges to be silver instead of white, spray-paint the entire cube silver. Otherwise paint the edges, corners, and circles white.

Mix the black and white paint to make a dark grey paint.
Paint the low area between the edges and the circle grey.

Mix the red and white paint to make pink paint.
Paint a heart in the center of each circle.

Step 5: Don't Let It Die

Whatever you do, don't let your companion cube die.
