3D-Printed Density Meter

🧪 3D-Printed Portable Density Meter 📌 Principle This density meter is based on Archimedes' Principle: "An object submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces." By measuring the object’s weight in air and when fully submerged in water, its density can be calculated using the formula below. This is actual measured data： 🧾 Materials Needed M3×20 screws (2 pcs) + M3 nuts (2 pcs) Digital scale Buy on Temu 🔗 Foldable water cup Buy on Temu 🔗 3D-printed structure (printable components) 📽️ Tutorial Video Watch the tutorial on YouTube 🔗
