Molecular Structure (Tetrahedral)

thingiverse

This is a unique combination of parts that can be assembled together to create an accurately proportioned tetrahedral model with 109.5 degree angles. I created this myself to help visualize the three-dimensional structure, as simply drawing Lewis structures does not fully explain its form. My teacher was pleased to use the model in other classes and I hope it will benefit students just like me. I'm planning on creating more models soon, including trigonal bi-pyramids, square bi-pyramids, bent shapes, T-shapes, see-saw shapes, and linear structures. My printer is a Wanhao Duplicator i3. I highly recommend printing at 0.1 layer height and using supports for spheres. Infill should be at least 10% for the pieces to fit together properly. If they don't fit perfectly, glue can be used as an alternative. Print Settings: Printer Brand: Wanhao Printer Model: Wanhao Duplicator i3 V2 Rafts: Doesn't Matter Supports: Yes Resolution: 0.1 Infill: 10% and up Standards: NGSS CCSS Overview and Background Lesson Plan and Activity: The print can be made small enough to create kits for whole classes. Materials Needed: 3D printer PLA or ABS filament
