About this 3D model
I have seen the Articulated Lizard model in Thingiverse. It is very interesting. If we add some simple tools that can make it alive, it should be better. I add small holes in the Articulated Lizard body. Link these holes with the transparent sewing thread that the diameter is about 0.2 mm. Now you can play with it. Have fun.
