This is a mod of Jap's High Quality Nose Pliers. I really liked the design but they werent as tough as i wanted. I modified them:
Shrank the snap down slightly so the 2 halves would fit together without breaking.
made the handles fatter with a truss structure inside so they wont bend.
Braced the jaws so they are stronger.
Increased the size of the central joint.
- Put a wide gripping area in the jaw for bigger objects.
Of course, they arent as strong as steel pliers, but they should be good for light duty use. I wanted them for handling fragile things made of plastic or wood.
Snap together with a vise. If the fit is too tight you can scale one of the halves to make it fit better. Scale the socket side up or the plug side down. 1 percent increments should be good. I did most of the work is tinkercad. I changed the size of the hole in the socket side and the plug using Blender. I usually print this at 150% on my Afinia
