Park Tool TS2 Extensions (TS-2EXT.2 replacement)

I own a very old (original) Park Tool TS2 Truing stand. I wanted to be able to true my 29er wheels without having to remove the tires, or spend $55 on their adapters. Print two of these in a sturdy material (PLA should be fine, increase extrusion width & # of perimeters), and secure them with a machine screw, washers, and a nut.
