Cup holder for Doona strollers. Can fit larger jug style water bottles with the handle notch. Or can be used with smaller bottles / cans. 

Attaches to the notch near the top of the handle.

It can be a little noisy if you have a can rattling around on your walk, so I included a simple insert model that can be printed out of TPU or other softer material to dampen vibrations and sound.
