Stencil Hóa Hữu Cơ (Organic Chemistry Stencil)

This is a stencil to draw organic chemistry molecules like benzene rings, hexane rings and all kinds of other carbohydrates. You can also use it as a ruler. I printed it with a Prusa XL with black and white filament but this isn't necessary. The numbers of the ruler might be hard to read without any contrast though. The holes on the side are for standard isometric binders.
