water bottle 3d model

Create a detailed, school-safe 3D printable design for a water bottle with a hidden storage compartment. The total bottle height must be 290mm with a diameter of 70mm and smooth, rounded edges for safety. The bottle must contain two completely separate and sealed chambers. The top chamber is for drinking water only and must be non-toxic, food-safe, and fully sealed so it cannot leak into the storage area. The bottom chamber is a hidden storage compartment approximately 95mm tall, suitable for holding a credit card, money, and small keys. The storage compartment must be fully enclosed inside the bottle structure and must not interfere with the water chamber. It must include a secure external access door on the side of the bottle so users can store items without touching the water. The design must be leak-proof and secure. The main version should be transparent so the compartment is visible from the side. Include a grip-tight side handle, friendship charm, and Rhode lip balm holder.
