Introduction: How to Make a Companion Cube

Step 1: Gather Your Supplies.

You will need: perler beads (white, pink, dark grey), a hot glue gun (with glue sticks), perler pegboards (a circle and a square one), an iron, and ironing/wax paper.

Step 2: Make the Corner Pieces.

Make the white corner pieces by placing the beads on the pegboard. There are 3 different pieces per corner - these 3 pieces will snap together and make one corner. You will need 8 corner sets total. Use the picture above for reference.

Step 3: Fuse the Beads.

Fuse the beads by placing a sheet of wax paper over them. Gently iron them at medium heat for a few seconds. Flip the fused beads over once one side is finished, and fuse the other side. Both sides need to be fused! *Make sure you don't over melt the beads or they will be unable to "snap into place" for the 3D effect.

For a more in depth explanation of the fusing process, visit the linky.

Step 4: Make the Edge Pieces.

There are 2 pieces in one set. You will need 12 edge sets. Use the picture for reference. Fuse when finished.

Step 5: Make the Circles.

You will need 6 circles total. Fuse them when finished. Use picture for reference.

Step 6: Make Square #1.

You will need 2. Fuse when finished. Use picture for reference. (The outline is just for emphasis on the detailed "teeth" portions.)

Step 7: Make Square #2.

You will need 2. Fuse when finished. Use picture for reference.

Step 8: Make Square #3.

You will need 2. Fuse when finished. Use picture for reference.

Step 9: Make the Hearts.

You will need 6 total. Fuse when finished. Use picture for reference.

Step 10: Snap the Corner and Edge Pieces Together.

Step 11: Snap the Grey Squares Together.

You will now have a 3D cube. *Be gentle, don't break the "teeth" pieces while snapping them together.*

Step 12: Hot Glue Hearts to Circles.

Make sure the hearts are centered on the white circles. Hot glue them together.

Step 13: Glue on the Corners.

Glue the corner pieces to the 3D cube.

Step 14: Glue the Edge Pieces to the Cube.

One per edge. Align them with the pink lines on the square faces.

Step 15: Glue to Heart Circles to the Cube.

One circle per side. Voila!

How Big is the finished project? I'm looking for a suitable Companion cube in a Nerf war with a companion cube ecort mission.

I no longer have this cube in my possession but I believe it was approximately 5in x 5in x 5in.

My parts keep snapping :(

How do you connect the 3 corner pieces, because I'm going nuts right now. I think my brain is broken.

Did you ever get this done? I am stuck on the walls. First wall piece, lower left corner in outline picture, has a single bead whereas the filled version has a double bead "tooth" which is throwing me off.

the link doesnt work anymore, but this one should do :)

I used this for a friend's birthday present - I had the top lift off along with the corner and edge pieces, and then I filled it with M&Ms.

That sounds cool, I bet your friend loved it.

The instructable is great but you should credit the original design http://www.flickr.com/photos/saturnines/4021291232/in/set-72157623066198545/

You're the second person to say that and again, IT'S RIGHT THERE IN BIG BOLD RED LETTERS WHO SHE GOT THE PATTERN FROM. Please be sure to read fully before saying credit was not given.

Wow very nice. Now if only I had any of the materials I would consider making one myself.

Curious, how much would you say all of the materials cost total?

1 reply

The beads themselves may have cost around $8-$10.

How do you connect the 3 corner pieces?

Wait until the pieces have cooled down back to room temperature. (If they are flexible they may snap if to much force is applied.)

Ohokay thanks :), cause I snap and it broken when I didn't use any force..

Its possible that you didn't melt the beads enough if it broke that easily.

I snap them together, but the corner side broke..

Well I don't have it with me atm, but i'd say its a bit smaller than a 12oz coke can in height. Next time I have it i'll give the dimensions.
