I got a new milling vice for my mill, but it didn't come with a wheel to roll the jaws in and out. This just slides on over the acme screw's 19mm / 3/4" hex drive so I can quickly spin the jaws in and out. I wouldn't use this design to actually do the workholding tightening tho, it's mostly just so I can move the jaws on the insanely tight thread lead screw faster than the socket wrench I normally use.
I included models for 3/4", 7/8", and 1" hexes on whatever acme screw your vice may use. I also included the .STP files for each size, so you can change the hex size as needed.
If you want to build this, you'll need:
1 - 608RS bearing
1 - M8x1.25 80mm socket head screw
3 - M8x1.25 nuts @ 13mm hex size
2 - M6x1.0 22mm bolts
2 - M6x1.0 flange nuts
The bearing presses into the wheel, and is pinned in place by the two M6 hex bolts. The spinner handle is setup like this:
nut | bearing | nut | nut | printed handle section
the double nut is to give clearance for the two M6's that pin the bearing in place.
I highly recommend printing this from some kind of stronger material, not just PLA, & at 100% infill on the wheel. The hex that engages the acme screw will get worn out over time if your material isn't stiff enough. I did this with ASA, but something like PETG would work. PA6 or PA12 may even be strong enough to not need to pull this off and finish tightening with a real wrench.
