This is a tuned remix of ecoiras' print-in-place Predator Action Pliers. I didn't find it on MW so I'm uploading it. All the credits for the original creator, of course.
Printed on x1c:
Generic Yellow PLA
2 walls
20% gyroid infill
No support
No brim
Working like charm, is just for fun, not for grabbing heavy things.
Edit: I added the timelapse. I will upload better photos soon.
