CD gripper for a CD changer

This is a PASSIVE gripper for a CD changer created to eliminate an actuator.
As you push it into a CD, it spins an eccentric on the shaft opening or closing jaws.

It needs further work! The return spring is not able to turn the ratchet.
Since it needs extra work, I am uploading Freecad files only (no STL).

The gripper requires 3 springs from ball-point pens and a pin made out of a paper clip.
It can be attached to a robot arm or an actuator of your choice.

Print with 0.1 layer thickness or lower. No supports or rafts are needed. 15% rectilinear infill works for me.
