Quite a few years ago – maybe even a decade – I signed up for and received a free 3D printed adjustable wrench. It was meant to be a proof-of-concept advertisement for rapid prototyping, from Stratasys, if I recall correctly.
Over at Thingiverse, user jsteuben designed something of a similar spirit – adjustable tongue and groove-style pliers that really work. His 3D printed adjustable pliers are fully functional, and since they’re made of plastic they can also possibly be used in non-marring applications.
You wouldn’t want to use plastic 3D-printed pliers for demanding applications, but there’s a certain appeal to them. They probably weigh a lot less than steel pliers, although that also reflects on their strength.
What I’m thinking is that these would make for excellent children’s pliers. Toy pliers are often made of colorful plastic, but lack the look and functionality of real pliers. These are somewhat closer to real pliers, plastic constriction notwithstanding.
The designs can be scaled up or down to suit your needs or preferences.
