Electron Orbital Modular Kit

This modular 3D Printed Electron Orbital Set is designed to bring chemistry off the page and into your hands. This set includes all the components necessary to build the s, p, d orbitals, providing a tactile way to visualize complex atomic structures.

Key Features 

• Modular Design: Features a "Build it yourself" system where individual lobes, rings, and axes snap together.
• Educational Visualization: Allows for the assembly of "Combined" models to show how multiple orbitals occupy the same space around a nucleus.

• Easy Assembly: Uses standardized connectors and a stable base with X, Y, Z axis labels for accurate orientation.

  

Technical Specs & Print Settings

To ensure the components fit together snugly, the following design considerations were applied:

• Tolerances: Holes feature slight chamfers to improve grip and ease of assembly. The model is designed for printing with 0.4mm nozzle, 0.2mm layer heights, with tolerances of ± 0.05mm.

• Material Optimization: Tuned specifically for "Generic" PLA, Bambu PLA Basic, and Bambu Matte PLA. 

  *Note that Matte PLA tends to run slightly looser than its Basic PLA counterpart, and PETG runs tighter.

• Supports: Support structures have been manually painted on where necessary to ensure clean overhangs without affecting the fit.
• Walls & Infill: Recommended 3 walls for strength / quality feel, 2 walls for lighter parts. 10% adaptive cubic infill.
• Adhesion: Highly reccomended to use supertac plates / wash PEI build plate thoroughly + increase temperature for teardrop orbitals.

Assembly

• Insert the vertical Z-axis pole into the X/Y base plate.
• Snap the spherical connector hub onto the top of the Z-axis.
• Use the axis markings on the base to ensure your lobes are in the correct mathematical orientation.
• Slide the specific orbital lobes into the slots on the connector hub.

EDUCATIONAL USE CASES

1. Visualization of Electron Clouds & Orbitals

Most students struggle to understand that orbitals are not "tracks" (like planets), but 3D regions of electron probability.

• 3-Dimensionality: By handling the s-Orbital Lobe or the teardrop Orbital Lobe, students can rotate and inspect the shapes from every angle, making the concept of a "probability cloud" concrete.
• Use the dz² Toroid (Donut Ring) to show how the dz² orbital is unique, providing a physical explanation for its distinctive shape.

2. Mastering 3D Axis Orientation

Coordinate geometry is the foundation of orbital chemistry. This kit uses the X/Y Axis Base and Z-Axis Pole to make spatial orientation intuitive.

• Spatial Reasoning: Construct various models (single, or multiple) and challenge students to identify orbital orientations.
• Step-by-Step Construction: Have students construct a single p or d orbital.

3. Mastering Full Orbital Shells

The modularity allows for "layering" to show how multiple orbitals occupy the same space around the Atomic Nucleus.

• Filling the Shells: Start with a single py orbital, then have students "fill the shell" by adding px and pz.
• Visualizing Overlap: This demonstrates how the different subshells nest together without interfering, creating a complete, high-density map of the electron shell that is nearly impossible to draw clearly on paper.
