Giant PLA Molecule, made from PLA
thingiverse
Another one of my old high school projects comes to mind, "Make a model of a molecule using things that represent that molecule". The bond angles might be (are probably) off, do not use the cover photo as a reference, this was almost 4 years ago and I'm not super into chemistry anymore. It's also massive. Took about two weeks of printing non-stop to complete it. I don't know how much it can be scaled down so the bonds still fit within the atoms.
