Bottle Capacity Indicator

English DescriptionOverview: A smart, 3D printed water level indicator designed specifically for sports bottles—ideal for those moments when it's hard to see how much water is left. The core concept features a buoy that floats on the liquid. As the bottle fills, the buoy ascends along a mast displaying a “FULL” indicator along with a line marking the maximum safe level, helping to prevent overflows.Key Features:Optimized Buoyancy: Crafted with 0% infill to ensure lightweight structure and maximum buoyancy.Structural Integrity: Designed with a minimum of 3 wall loops and reinforced by 3 to 4 top and bottom layers to ensure it remains watertight and stable over time.Mouth Diameter Compatibility: Specifically engineered for bottles with a 25mm opening, ensuring a perfect seal and optimal performance.User-Friendly Visual Cue: The rising buoy gives an immediate, clear indication of the bottle’s fill level, so you always know exactly when your beverage has reached its limit.Application:
