Print in color the flat design on a cardboard paper (I used 250g paper)

Then use the laser cutter to cut or mark the folding.

Cutting the printed file

Then you have the cut file with 2 colors:Red RGB FF0000 0.01mm to cut the paper and Blue RGB 0000FF also in cutting mode but with more speed and less power just to mark the folding.

It s basically the same file without any graphics (just red&blueLines)

On the printed sheet you will see a black corner it corresponds to the corner of the cutting job, so the idea is to put the laser spot just on this corner .

To fix the paper I use a cardboard sheet to cover the rest of the laser working surface and I put ventilation On which blocks my paper by aspiration.

I put the laser spot on my corner the I move the head in one direction and verify that spot is still aligned with the design (green line) then I put back the spot on the corner.

I created a material using the printer driver with 2 cuts speed&power Red->Cut Blue->Mark for Folding.Then I just have to drag and drop the design on the cross which represent the laser spot, then Go.



Assembly

Prepare 11 strips of double side Tapes.

Fold all the line to make sure that your dice will cleaned edges. Then proceed from left to right one by one grouping 5 triangles together.
