figure ii:  

a series of bilaterally symmetric prints are composed of a pectin chitosan infill base layer with a cellulose lattice surface layer. the cellulose surface layer is generated to align to specific vectors that encourage creasing the surfaces along predefined ridges. two sets of 3 identical prints are clamped along the wetted central pectin spine to adhere all surfaces together

figure iii:  

the cellulose surface layer is generated to align to specific vectors that encourage creasing the surfaces along predefined ridges. the center lines of each print have a region of pectin infill printed above the cellulose lattice. regularly spaced holes on the print allow the surfaces to be clamped and joined together
