This is an update of my earlier tiny pliers that improves the spring and also includes a needle-nose version. With an overall length of about 90mm, you can stash these everywhere they'd be handy.

The stubby version has grooves for grabbing small hex nuts. The needle-nose version is great for grabbing wires or other tiny things. Both versions have an integral opening spring. Both also print-in-place without supports. (The needle-nose version has some tiny built-in supports at the tips that break-away easily.)

Print using PLA with 0.2mm layers. After printing, just give them a good squeeze to break the jaws free.
