A pad that clicks over the screw foot of the vice, so it does not damage my table too much.

I always loved making, braking, fixing, mending and abusing things. Especially the latter: making what I need by using things that were not intended for that purpose. A 3D printer is one of the nicest tools I ever owned: you figure out what you need, you find something that sort of works and then make the parts to bridge the gap. Custom parts for whatever purpose at barely any cost at all; maker heaven.
