String Swing Guitar Rack - Rail End Caps

I just picked up a string swing to display/hang my guitars on the wall, and I didn't like the end caps that came with it that required sticky tape to fasten in, so I created these printables that will not leave any glue residue. They just slide (tight fit) into the side, and can be removed fairly easily if needed.I will be making many other string swing accessories in the future, but this was my first. (and my first freecad project as well)
