This is a 3D model showing a closeup of the cutout in
the aluminum that allows us to slide the plastic 2 liter
bottles in and out of the supporting bracket.
Notice the hole directly to the right of the U shaped
notch (on the same surface) as this is where we will be
putting the threaded rod through, to support each layer
of farm fountain.
The holes for the threaded rod are .25 inches. The U Shaped
notch is 1.04 inches wide and 1.20 inches deep.
The angle aluminum is 1.5 inches wide by 4 feet long.
