Watering/Measuring Jug for plants

thingiverse

This is a versatile model of a jug featuring lines to enable precise watering of identical volumes of water in each pot daily, perfect for plants, though equally effective for other purposes. Although measurements aren't marked on the sides, lines are present on both sides, allowing you to measure the volume of water by the line it reaches and providing visibility from inside so you can accurately fill up to that line since most filament is not transparent. You'll need to scale it up depending on your intended use, but size isn't a critical factor.
