T-handle organizer

Metric and Imperial T-handle sets: 2.5, 3, 4, 5, 6, 8, 10 mm and 1/8, 3/32, 7/64, 5/32, 3/16, 7/32, 1/4", 7 of each. The top piece is the download file, to make the bottom piece delete all the interior holes leaving just the 4 perimeter holes. At the corners use 1/4"-20 threaded rod with 4 washers and nuts per rod. Cut the 4 threaded rods to 6", a Dremel and a cutoff wheel or hacksaw will do the trick. Make the ends square, and chamfer the ends so the nut threads on the rod easily. Assemble the threaded rod end on the top surface so it sits below the nut surface to ensure there are no sharp edges exposed. Use the nuts in the bottom section to level your tool holder.
