rc tank claw/grabber

This is a claw I designed for a tank I have printed off here ( will post pictures once completed) This one was made simply because I only had two servos on hand so will close,open and up,down. I used a spring from a bic pen to return the claws to open position and fishing line attached to the claws and pulled by servo for closing. Cuts of filament and a little superglue to attach pieces together.
