Bohr atom model

PROJECT PROPOSAL: THE INTERACTIVE BOHR ATOMIC MODEL"The Interactive Bohr Atomic Model is a fully 3D-printable, snap-fit educational tool designed to bridge the gap between abstract quantum physics and tactile STEM learning. It allows students to physically 'build' elements, transforming textbook diagrams into a hands-on classroom experience."## Innovative Design Features (100% 3D Printed)Zero-Hardware Assembly (Snap-Fit & Dovetail): The entire model—from the central nucleus hub to the concentric electron shells—interlocks seamlessly using smart plastic tolerances, snap-pins, and dovetail joints. No screws, no glue, and no external hardware are required, maximizing the efficiency and purity of 3D printing technology.Customizable & Reusable Element Card System: Instead of wasting filament to print separate cards for every single element, the model features a blank 3D-printed base card. Users simply write the element's name, atomic number, or electron configuration on a standard slip of paper and stick it onto the card (using tape or a sticky note). This paper-on-card assembly then slides into a dedicated dovetail slot on the model's base, making the system infinitely reusable for all 118 elements.Mechanical Kinetic Electron Tracks: Instead of static parts, the concentric rings representing the electron shells feature a custom-designed U-shaped captive track. Students drop standard 3D-printed marbles into these tracks to represent electrons. The marbles can spin and roll freely around the nucleus, simulating the continuous movement of electrons.## Classroom Application & Interaction (The STEM Learning Flow)Step 1: Write & Stick the Element: The student takes the blank 3D-printed Element Card. They write the details of their chosen element (for example: Oxygen, Atomic Number 8) onto a small piece of paper, stick the paper onto the card, and then slide the card into the base slot for clear reference.Step 3: Construct the Nucleus: Based on the information on the card, the
