Here are files for onefinity wasteboard. The ruler was created for laser, but could be cut with vbit or engraving bit. if using laser, offset correct amount if using zero zero(home) as location.
The grid is 2" x 2" grid, that I used vbit on to cut. cut as fast as you like. i chose .1 deep to have good edge to grab work when laying down and getting square.
