modular platform 3d model

Create a clean CAD-like 3D model of a single-block horizontal ELISA laboratory workstation, designed for FDM 3D printing. The object is a rectangular, low-profile base with smooth filleted edges, matte plastic appearance, light gray color. Layout from left to right (right-handed workflow): – Left: recessed rectangular niche for a standard ELISA wash tray, with a shallow 3–5° tilt, liquid-retention rim, and a small drainage groove. – Center: recessed holder for a standard 96-well ELISA microplate, with a 5–7° ergonomic tilt, low side lips, and a small corner orientation marker. – Rear-center: flat elevated platform to hold a pipette tip rack (96-tip box), with low perimeter guides. – Right: integrated cylindrical pipette tip waste container with an internal conical taper. – Front-right: flat platform for a digital laboratory timer with shallow retaining lips. Design requirements: – precise geometry, straight edges, no organic shapes – uniform wall thickness suitable for 3D printing – rounded internal corner
