3D model description

What kind of pliers do you use in math class? Answer: Multipliers!

These pliers are designed to be easy to print, moderately strong and they have built-in springs to self open when you release pressure on the handles.

Included are four variations:
A - Needle nose with jaw teeth
B - Needle nose with smooth jaws (no teeth)
C - Blunt nose with jaw teeth
D - Blunt nose with smooth jaws

Each pliers consists of two parts - a male and female side.

Supports:

The needle nose variations (types A and B) need supports. Supports are only needed under the nose section of the male part.

The blunt nose variations (types C and D) do not need any supports.

Assembly:

(1) Align the hinge notches of the two parts and press them together (sightly rotating back and forth can help find the right alignment). For reference the notches align in almost the fully opened position.

(2) After the parts are pressed together rotate the parts back and forth until the movement is smooth.

(3) For best results disassemble the parts and add a small amount of 3-in-1 oil to the hinge area and reassemble.

Design Motivation:

I normally clean the nozzle after loading filament or right before printing with a pair of pliers. After a few months I realized I had wore down the side of my brass nozzle because the pliers were made of hardened steel. So I looked around for a good pair of pliers to print. I had two requirements: (1) they self open and (2) they were the needle nose variety to help me reach the nozzle easier. I looked around and didn't find any models I liked so I decided to design my own.
