Coffee Cup Beltclip #1

Ever been carrying a coffee cup and wished you had both hands free?
This design is clearly not perfect; I'd rather have the holding ring at the other end so the centre of gravity is better placed, or to have a second ring to hold the base of the cup, too. Later iterations may see some design improvements! Or, do it yourself to spare me the trouble! ;)

Hope it doesn't spill on you! I make no promises.
