Wood Working vise Rack stopper

Rack stop is used in a wood working vise in the opposite side form your work piece. this keeps your vise jaw relatively square against your workpiece for better holding. 

7 different thicknesses  from .25" to 1.75"

I have not printed this yet, but you'll want to print it pretty strong since it will be under quite a bit of pressure from the vise.

Print with the large flat face down
