Molecular Geometry (simple stick figures)

I also have 3mf files for the surrounding atoms and lone pairs but cannot upload multiple 3mf files. But duplicate without auto arranging the plate and follow the support instruction should allow efficient use of build plate space and minimize filament use. 

Larger surrounding atoms may be easier to build and remove.

Gyroid infill @ 10%

For central atoms: 

• support (tree) at critical regions only to minimize filament use. 
• support for PLA filament used for support.
• arranged orientation to avoid support in holes and minimize post printing workup

For surrounding atoms:

• support (tree) at critical regions only to minimize filament use. 
• same PLA used for model used in support.
• arranged orientation to save filament use. Invert 180 degrees would improve appearance of the surrounding atoms.

For lone pairs:

• support (normal) on build plate only. 
• same PLA used for model used in support.
