A regular vice is great if you want to clamp rectangular objects, but it can fall down a little with more complex shapes. Inspired by an ancient vise [Chris Borge] whipped up his own 3D-printed fractal clamping tool.
The inspiration for this one comes from the [Hand Tool Rescue] video that shows of the clever mechanism. The vice uses a series of interlocking parts that can freely articulate to grip the object of interest via several protruding fingers. In reproducing the design, [Chris] had some issues initially with the joints, but settling on a dovetail similar to that of the original metal vice which got things working nicely.
[Chris] notes that while the design works, it could still use some refinement. Silicone or rubber tips on the fingers could give the vice better grip, and there remain some flexural issues that could be improved. Overall, however, it’s a useful table vice for small jobs on weird shaped things. We’ve seen 3D-printed vices before, particularly in the PCB vice space, but the grip scheme user here is totally unique.
