This is chewiedies's duckboard model, except the edges of his model didn't match my keyboard's case so I remixed it to just be a rectangle. This is a modification of the v9.2-LidwithoutInserts.stl model, and the rectangles made to straighten the roundover of the original model may clip into the cylinders made for the screw. I just plan to drill those out, but it is up to your discretion if you want to continue modifying to clear those holes.
