Step 1: Layout.

From L to R: tongue and groove locking system, unknown joint, mitre joint, curve joint.

Step 2: Unknown joint.

Although the thickness of the X-Board is 10mm, the material folds in on itself.
Therefore the width of the cut should only be 9mm wide.

Step 3: Mitre edge.

Similarly, instead of a 20mm (10mm x 2) width cut, a 18mm (9mm x 2) cut would be more accurate.
This is because of the 1mm 'skin' of the X-Board.
The challenging part of this step is getting a crisp and sharp edge.
This can be done by scoring the inside of the X-Board before folding.

Step 4: Curved edge.

To acheive a smooth radius, the X-Board has to be bent slowly and carefully.
Scoring the X-Board would help acheive this, as well as controlled compression/crushing of the 'honeycomb' stuff inside the X-Board (after the skin has been peeled off).

Step 5: Completed cube.

Dimensions: 6mm x 6mm x 6mm

Step 1: Star-shaped folds.

This is a repetition of star-shaped folds, each unit interlocked with next one surrounding it.

Step 2: Fanning out.

Each individual unit is then fanned out, automatically locking itself into place with the next connecting unit.

Step 3: Completed model.


Step 4: Side view.
