A collection of scientific correct 3d models of molecules! The relative distances from atom to atom, the relative size of the atoms to each other, the angles of the bonds and the amount of electron bond are scientifically correct(the van der Waals radius was used). Each download consists only of one model of the molecule.
The collection consists of following molecules:
Adrenalin(C9H13NO3)
Carbon Dioxide(CO2)
Carbon Monoxide(CO)
Dibromine(Br2)
Dichlorine(Cl2)
Dihydrogen(H2)
Dinitrogen(N2)
Ethanol(C2H6O)
Hydrogen Peroxide(H2O2)
Iodine(I2)
Methane(CH4)
Methanol(CH3OH)
Nitric Oxide(NO)
Nitrogen Dioxide(NO2)
Ozone(O3)
Water(H20)
and more coming soon...
The amount of faces and vertices is high enough to give you a carefree experience that works for close ups as a presentation and shots that are a little bit further away.
All formats that do allow vertex color, groups and/or materials for exports have it enabled.
For the color assignment the CPK molecular model, designed by Robert Corey and Linus Pauling, was used.

This STL file is compatible with most FDM 3D printers (Creality Ender 3, Prusa MK3S+, Bambu Lab, etc.) and resin printers (Elegoo, Anycubic). Check the original page for recommended print settings and materials.
This is a premium model priced at on cgtrader. Premium models often include higher detail, multiple parts, and print-tested files.
Most STL files can be modified using free software like Blender, TinkerCAD, or Meshmixer. Check the license on the original cgtrader page to see if modifications are permitted by the creator.
