Note [April 28, 2024] : See the remix below for a version with a stronger crank handle :

This speed handle was made for the 4" (100mm) vise I use on my bench-top mill. Of course different vises have different sizes and shapes for attaching a vise handle, so this may or may not work for your vise.

My vise came with a long metal detachable handle, but this is inconvenient to use when setting up material in the vise. This speed handle is intended to be used to make it easier to initially position work in the vise as it makes it easier to tighten or loosen the vise as necessary; after that the metal handle can be used for final tightening of the vise.

Note that the crank handle on this is fixed (non-rotating), as I opted to keep the design simple.

Here is more information on my vise :

The handle fitting for the vise is hexagonal - 15mm across the flats and 25mm long.

I printed over-all with 10% linear infill and 2 perimeters, but I used modifiers to add additional infill and perimeters around the socket, and additional perimeters for the crank handle.
