This is the one I had beforeMini pliersIt's an upgraded version that improves the spring and also adds a long-nose version. The overall length is about 90mm, and you can place these pliers anywhere, which is very convenient.

The short and fat version has grooves that can clamp small hexagonal nuts. The long nose version is very suitable for clamping electric wires or other small items. Both versions have an integrated spring. Both versions can be printed in one piece without the need for supports.

It is recommended to use PLA material with a layer height of 0.2mm for printing. After printing is completed, you just need to squeeze it hard to open the clamp.
