Bottle stand for plant watering

Heading out on vacation and needed an auto dispenser for trays of vegetable starts, so I found a chicken waterer, removed the bowl in Design Spark keeping the part that screws onto a water bottle, and then added legs.  It's sturdy and steady and works exactly as desired with 3½" tall starter pots.  Smaller pots might benefit by being elevated in the tray with a layer of sand so they don't get waterlogged. 

I print this with a .6mm tip and .4mm layers, 5 top, bottom, and side layers, and 25% infill with PETG at 70C bed and 235C top end. I can fit up to 9 at a time on my Ender 3 bed.
