process 2 

 create the waffle shape of the model

1. download the model created by 123d catch online

2. make the model solid using the computer and meshmixier since the model created by 123d catch is just a skin without solid parts

3. open your result by computer program 123d make

4. using the 123d make to create the waffle shapes 

5. open the file created by 123d make by illustrator. 
change the line color and thickness to red and 0.001(if you do not want to use laser cut in uni things would change since different machine may have different setting), respectively.

6. using the lazer cut machine to cut the shapes and assemble it 

tips: 
a: the sheet size should be changed since unsw laser cut machine is suited for 300*600. 

b: if you want to cut a 3mm thick plywood board. you should set your thickness in 123d make in 3.2mm or 3.3mm a little bit thicker.

like above, otherwise your waffle shapes will be extremely difficult(what i mean, impossible) to perfectly set in. that is my first attempt. yeah, it is ashamed to say but actually its a failed one.
