This conical deep‑irrigation watering device is a 3D‑printed creation designed for the care of potted plants. The model is printed as a single, monolithic part, eliminating the need for gluing or assembly. It features a tapered, spike‑like structure: the base is a flared water inlet, which narrows upward into a conical shaft adorned with circular perforations for slow, even water seepage. At the tip, a pointed cone allows direct insertion into the potting soil. To use, insert the pointed end into the soil and pour clean water through the flared base; the water then percolates slowly through the hollow channels in the shaft, delivering moisture deep into the root zone. This approach prevents rapid evaporation of surface‑applied water and ensures adequate hydration for the plant’s roots. The wall thickness has been reinforced, and all edges and corners have been rounded to eliminate sharp angles.
