Use LoboCNC recommenced settings.
I added eyes and 2 sets of teeth, the first when spring is engaged. Seeing how this thing is flying around I left the teeth blunt to avoid potential injury. The second when folded back. The second set of teeth are just countersunk to keep strength of body.
Legs are untouched.
Edit: I forgot to add, Dont leave this thing stored in coiled position, it will loose all of its spring.
Thanks to LoboCNC for the amazing design.
