Protein Skimmer

An in-sump protein skimmer: a 120 mm translucent acrylic cylinder 500 mm tall on a flat black base plate, with a faceted cone neck, a screw-off collection cup, a black pump block clamped to one side and a gate-valve standpipe on the other.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
