Perfect for a desk or window-sill, this planter allows your herbs and greenery to continually sip water from a reservoir in the bottom rather than being stressed by wet-dry cycles over time.
The inner sleeve will lift right out of the device easily, and the stylish integrated spout allows you to either add water as needed, check the level any time, or pour out old water for cleaning.
I've tried to take advantage of all of the production benefits offered by 3D printing, using generous curves and filets where possible, things that would be prohibitively expensive to achieve on a clay or metal planter produced by traditional means.
I'm dedicating this part to public domain, make any use of it you wish, including commercial sales :)
