This is a self-watering planter designed to fit inside the Ikea Skadis tin with a reservoir and capillary mechanism inspired by the Utilitarian Planter by @jack_hmr. Thanks to @Unknownkwita for the starting model.
Cutaway view of internals in fourth photo. Add water in the rear slit.
As with any model that's intended to be waterproof, print with extra perimeters, check your seam locations to make sure they're staggered, and bump up your filament extrusion multiplier a few percent. .3mf file with all print settings is attached.
The author remixed this model.
Added self-watering reservoir and capillary mechanisms. Removed weep holes and feet.
