Hello! First, I would like to thank you for visiting my Instructable. This is the “Cardboard 3×3 Rubik's Cube", and like the last “Cardboard 2x2 Rubik's Cube” I made, it's fully functional!

Supplies

108 circular magnets
Template
All-purpose glue
Hot glue
X-acto knife or scissors
Cardboard

Step 1: Print Out the Templates

To commence this project, we must print the templates. Make sure to use Adobe Acrobat, and when printing select the option of "fit".

Step 2: Glue on Cardboard

Now that you have printed the templates, we must glue the papers on top of the single-ply cardboard.

Step 3: Cut Out the Cardboard

Now we have to cut out the template, but I recommend that you glue everything well so then the paper will not ruin the cutting and make the job harder.

Step 4: Check If You Have Placed the Magnets Correctly

On the template there are circles with two different colors, red (positive) and blue (negative), that's where the magnets need to go. Hot glue the magnets in the correct position, and pay attention, or the project will not go as planned.

Step 5: Assemble the Boxes

Now that we have the magnets glued on with the right magnetic poles, we can start the cube assembly. This job is really simple, just fold the boxes and at the same time glue the box together like a regular paper box.

A small tip that I can give you is to draw faintly with a pencil a darker side for positive sides of magnets and a brighter side for the negative ( or the other way around), it can help during the actual assembly, when trying to build the actual cube.

Step 6: Assemble the Cube!

Now that you have all of the boxes, we have to assemble the actual cube!

Take the unit piece (box with magnets on all sides) and connect the centerpieces (box with four magnets) and put them on each side of the unit piece. Now you should have something looking like picture 1 Now attach the edge pieces (box with three magnets) and place them by connecting each of them to the unit pieces. Now you should have something looking like picture 2. Now you just have to attach the corner pieces to well, the corners. Now you should have something looking like the picture 3.

Step 7: Glue on the Stickers

After the assembly of the cube, the next step is to glue on the "stickers". It isn't difficult but there's a specific order for the colors of a Rubik's cube, so above there is a color guide to help with the "stickers".

Step 8: Congratulations!

Congratulations on building the Homemade cardboard 3x3 Rubik's cube! Once again, thank you for viewing this, and please vote for me if you liked it, and don't hesitate to ask questions if you need to! Bye!!!
