Double Bottle Funnel
thingiverse
Human: I despise wasting a single drop that gets stuck in a bottle. This ingenious design lets you place the nearly empty bottle on top and the new one on bottom, allowing all remaining liquid to flow into the fresh container. Ketchup, shampoo, oil - it works for everything! This clever creation was crafted with Tinkercad. Edit it online at https://www.tinkercad.com/things/ggb5ZxZknrI
