The second file is the end cap. There is hole for the placement of a screw eye or eyebolt.
The third file is a the cone itself in case you want to add your own custom shoulder.

Almost all of the upscales have files that have been split up in to two or more pieces so they can be printed on smaller printers such as the Creality Ender 3 which has a max Z height of 220mm.

The 5.38 inch LOC/Precision tubing upscale is divided into three pieces that are about 250mm in height or a little less.
