Self Watering Geometric Planter

Embrace the slow rhythm of plants that water themselves with this Self Watering Geometric Planter, a dodecahedral pot that hides a reservoir base inside its own silhouette. The twelve-faced top sits on a matching half-dodecahedron reservoir, the two parts stacking into one clean Platonic-solid shape until you lift them apart. The matte stone-effect finish shown in the photos makes both pieces feel less like 3D prints and more like cast concrete, the kind of weight you want next to a windowsill plant.

Design & Concept

I designed the Self Watering Geometric Planter as a study in how much function can disappear into a single sculptural shape. The dodecahedron is one of the five Platonic solids, the kind of form mathematicians and Renaissance artists have been drawing for centuries, and it turned out to be the perfect housing for a self-watering planter: each pentagonal face gives the eye a flat surface to rest on, and the horizontal split between the upper pot and the lower reservoir reads as a clean equatorial seam when the two halves come together. The bottom faces of the upper pot are perforated with a dense pattern of small holes, so water wicks up directly from the reservoir whenever the soil needs it. No rope, no pump, no power, just the geometry doing the work.

Key Features

• Self-Watering System: The upper planter sits on a hidden reservoir base, and water wicks up through a dense perforation pattern on the planter's bottom faces. No rope, no pump, no power.
• Dodecahedral Silhouette: Twelve flat pentagonal faces stack into one of the five Platonic solids, a sculpture on its own even before the plant goes in.
• Watertight Reservoir: When printed at 100% infill density with a rectilinear pattern as recommended, the lower half holds water cleanly without seeping.
• Plant-Forward Design: A sculptural form that disappears the moment a plant takes the top of the dodecahedron, then returns when the soil dries.
• Two-Part Print: Upper planter and lower reservoir print separately and stack together without glue or hardware.
• Stone-Effect Friendly: The faceted silhouette shines under matte and mineral-feel filaments, like the concrete grey print in the photos.

Printing Recommendations

• Infill Density: 100%, especially important on the reservoir half so it holds water without seeping.
• Infill Pattern: Rectilinear.
• Reinforcement Wall: Disabled.
