lab bioreactor 3d model

A simple 3D render of a small laboratory bioreactor system made by a beginner using Blender. The design shows a stacked setup with a rectangular microalgae cultivation tank on top and a dual-chamber microbial fuel cell below, supported by a basic metal frame. The shapes are mostly simple boxes and cylinders with slightly uneven proportions and visible joints. Materials are basic: transparent tanks with flat green, brown, and blue liquids, matte gray metal frame, and plain plastic pipes. The lighting is simple and soft, similar to a default Blender setup, without dramatic shadows or cinematic effects. The scene looks like an early-stage student project: clean but not perfect, slightly rigid geometry, minimal detailing, and no decorative elements. No labels, no text, no numbers, no bubbles inside the tanks. The overall appearance should resemble a beginner engineering prototype modeled manually in Blender, not a professional product render.
