aquarium plant holder 3d model

Design a functional 3D printable aquarium plant holder that attaches to glass using a suction cup. The holder should include a secure but gentle clamp or adjustable grip to hold plant stems upright without damaging them. The design should be compact, minimal, and suitable for underwater use. Include drainage holes or open structure to allow water flow. Use smooth edges to prevent harm to fish. The model should be optimized for FDM 3D printing with minimal supports
