Box with Woven Triangles I

Below you can find a precrease pattern and a photo tutorial of the collapse (for a clean fold). The model is designed around a 12×12 grid, of which 8×8 is the tessellation molecule. You can either fold the complete grid and then add the diagonal creases, or use the techniques described in How I precrease paper for tessellations in order to make a clean precrease without folding the grid first.

If you are interested in folding the corresponding tessellation, have a look at Woven Triangles Tessellation I instructions.
