The wife bought these cheap 1 gallon drink dispensers for an upcoming party at WalMart for $5 each, but they did not come with a stand or base so that you can't get a cup under them (unless they're on the edge of a table). I designed these in tinkercad and printed up a couple. Holds the dispenser up high enough to fit a solo cup under and pour a drink. It also is printed in 2 parts where the top part (the tray) has a lip on the bottom to snugly fit over the base so it doesn't slide off and it also has a lip around the top to hold on to the dispenser to keep that from sliding off the side.

This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/08xIXpYijyF
