oval ring sculpture 3d model

Create a highly detailed 3D model of a minimalist organic-shaped plant propagation vase holder, inspired by the OVALINEO design. The overall shape is a smooth, curved oval loop (like an abstract bean or infinity symbol), approximately 12cm tall, 8cm wide and 6cm deep, with a vertical cylindrical channel running through the center (inner diameter exactly 18-20mm to securely hold a standard glass test tube, depth at least 10cm). The outer surface has a soft textured stone-like finish, thick walls (minimum 8-10mm) for strength and stability. Flat stable base for standing on a table. Modern Scandinavian style, single solid model optimized for 3D printing, durable and functional for holding water-filled glass tubes with plant cuttings.
