(OPENSCAD SOURCE INCLUDED)
Hold your work piece down on Shapeoko 2 threaded insert wasteboard. There are three sizes, Small, Med and Large. You can edit the parameters in the openscad source and generate custom versions too!!
I modeled these from a set of commercial ones used on my Milling Machine.
