About this 3D model

This is my 3rd attempt of making a bionic claw. I declare this design as a FAIL, because i did not consider the weakness of the nylon material, so i can´t transmit big forces over the small lever! Anyways its a nice model and fun to play around with :) demovid: https://www.youtube.com/watch?v=vIAQCaxmLYA
