Slightly stronger grip 'predator action pliers'

thingiverse

I really liked Ecoiroas' original design for his 3D printed grippers, but I wished they had a stronger grip. So, I made a quick hack to shorten the piston rail gear and realign it slightly, giving me more room to apply force. This modification results in a noticeably stronger grip - although not extremely strong, as the gears do flex out with too much pressure. The jaws on these grippers don't open all the way back like Ecoiroas' original design, but they still open out about as wide as you would expect. PETG is probably a good choice for printing these grippers because it's less brittle than other materials.
