stormwater catchpit 3d model

A highly detailed, professional 3D engineering render of a rectangular stormwater catchpit insert. The outer shell is a rectangular bucket, wider at the top and tapering slightly towards a flat bottom. It has a prominent flat rim (flange) around the top edge. Inside the bucket is a central helical baffle, resembling a thick spiral water slide, designed to force water to swirl in a vortex. The spiral connects to the inner walls of the rectangular bucket. At the exact center of the flat bottom floor, there is a single circular drain hole. The material is matte grey, textured recycled 3D-printed plastic. On one corner of the top rim, there is a small rectangular mounting bracket holding a small electronic sensor. Clean industrial design, architectural lighting, white background, precise geometry.
