3D Printed Interactive Bohr Model

This is a DIGITAL (.stl) file for printing a 3D Printed Bohr Model kit that can be 3D printed to help students learn how to correctly place electrons in a Bohr Model for any element #1-18 on the Periodic Table.

What do you receive with purchase?
*(.stl) file for Bohr Model.
*(.stl) file for Electrons that will fit onto Bohr Model.

NOT included...
*Physical copy of Bohr Model or electrons
*1" whiteboard squares in the center of the model. I found these through Amazon here - https://www.amazon.com/dp/B077XSYNWZ?psc=1&ref=ppx_yo2ov_dt_b_product_details.

My story in 3D Printing & Science Education:
I have been a middle school science teacher in Houston, TX for a decade. I found a 3D Printer collecting dust in a box from an old colleague, started tinkering with it in my off periods, and have since fully implemented 3D printing and design into my regular State of Texas Science Curriculum. Some of my favorite projects are having the kids create 3D Printed Bohr Models in our Chemistry unit and having them develop Rocket Fins and Nose Cones for 2 L Water Bottle Rockets in our Physics Unit. My students learn 3D Design with the the free web-based CAD software "TinkerCAD."

My story in selling my products:
Tired of exorbitant, marked-up prices from Science Education Suppliers like Flinn or Carolina Biology, I decided to combine my hobby of 3D Design and Printing with my profession of innovative science education by creating products like this for my own classroom. A product like this would be $60-$80 on Flinn.

Bohr Model -
*20% infill
*no raft
*You can get about 9 of these Bohr Models off of 1 roll of 1 kg filament
*~14 hr print time on Ender 3

Electrons
*20% infill
*Less fails with a raft.
*If you print 23 electrons (18 max, plus 5 extra in case you misplace a few), you can print this amount about 25 times per roll of 1 kg filament.
*~4 hr print time on Ender 3
