I just purchased a vise from Carbide3d to go with their Nomad 883 CNC mill. It works well, but on my first print, the cutter came very close to the clamps on the vice. I designed these covers for the vise to print on a 3-d printer - this way, they serve as a sacrificial vice face - if the cutter starts spewing black shreds of plastic, I'll know I'm getting too close!
The covers are a tight fit, to prevent sliding.
Made with Cheetah3d, so that's what the .jas file is.
