Stumbled across this one recently, as the link and image suggests this is a fully 3D printable berry picker! Thought about buying one, but this one is rather convincing due to its features.

According to the guy who made it, "it doesn't damage the plants more than animals do". Plus he also made different comb sizes for different kind of berries. I know that these are banned in some countries from what I've heard, but in other countries they're quite needed as some berries grow and spread really fast.
