Rotate the model (click and drag middle mouse button) so you can see under the model, roughly where you'll want the base to go.
Press Shift+D (to duplicate the selection), then Z (to constrain movement to the Z axis), then move the selection roughly to the height you'll want the base to be at.
Press Enter or left mouse click when you're satisfied.
