SHELL . 123D MAKE

SECOND ATTEMPT 

Doing 36 panels of laser cutting is a waste of time, and Russell suggested that I should try 'Interlocked Slices' instead. Last time when I tried laser cutting, I have exploded the model to double its original size. I realised it was too big after I have laser cut it out and this time I reduced the scale down by 15%.

 I spent a lot of time changing around the slice directions and this was the best I could get, there were still some pieces highlighted in red by 123D Make indicating either there was a weak point in the slices or it does not join properly with the adjacent pieces. 'Interlocking Slices' does not like organic shapes such as this part of the shell but I had to go with this best result.  

This was the final laser cutting template edited in Adobe Illustrator ready to go.
