Adirondack Chair Clip-On Cupholder

This is four different versions of a cupholder designed to clip on to the arm rest of the plastic Adams Adirondack Stacking chairs commonly found at Ace hardware stores. The three versions are:
* A two piece clip together version designed for printing on the M3D Micro
* A one piece smaller version for the child size version of the chair
* A one piece version intended to fit the full size chair (untested because it doesn't fit on my printer).
* A one piece version with drain holes and support
