Gridfinity Holders for Alexandre Chappel's Hardware Design Boards

Alexandre Chappel has created a set of free 3-D printable boards for checking hardware tolerances and other parameters. He provided a holder for the metric screw sizes, but not for the rest.

I've created a 4x3 Gridfinity holder for the Hole Test boards and Test Boards, plus a 4x3 Gridfinity adapter version of the Hardware Design Boards holder.

I've included the Fusion 360 file for the Hole Test bin I created, but the Hardware Design Boards bin was literally created by merging a 4x3 Gridfinity baseplate with the original bin in Orca Slicer.
