Pliers - Self Opening

thingiverse

What kind of pliers do you use in math class? Answer: Multipliers! These pliers are designed to be easy to print and moderately strong. They feature built-in springs that self-open when pressure is released on the handles. Four variations are included: 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. The needle nose variations (types A and B) require 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 involves three steps: (1) Align the hinge notches of the two parts and press them together, rotating back and forth to find the right alignment. (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 before reassembling. I designed these pliers because I had worn down my brass nozzle while cleaning it with hardened steel pliers. I needed pliers that self-opened and were needle nose variety to reach the nozzle easily. After searching, I couldn't find a model I liked, so I decided to design my own. These pliers are printed using PLA, High Temp PLA, or PETG materials.
