Barrel Can Shot Koozie – 3D Printed Drink Holder | Bottom-Load Can Launcher

This isn’t just a koozie — it’s a working can-swapping machine. The Barrel Can Shot Koozie lets you load a fresh can from the bottom, automatically ejecting the empty can out the top. No removing the koozie, no fuss — just drop in a new drink and send the empty flying. Designed and 3D printed for smooth operation and durability, this koozie is equal parts functional, satisfying, and a guaranteed conversation starter.
