The gripper beaks can take the shape of the object they hold, like in this case an orange!

edit: Just to clarify this is not a remix of https://www.printables.com/model/118880-flexy-pliers-print-in-place-toy even though I will admid it is very similar! But I started this project just trying to print something I saw from festo and very quickly realized I had to create little hinges or it would not work.
EDIT: added clamps with a texture for more friction
update 02/10/2023: added new housing and clamp for a gripper with only 2 beaks

The author marked this model as their own original creation.
