I printed a 2,4,6-Trinitrotoluol molecule - better known by its abbrevation TNT - on my 3D printer this weekend. I constructed a tetraedic and a hexagonal basic shape using openscad and printed the atoms in different colors. I originally intended to connect the atoms using double sided tape but the molecule got pretty unstable and fell apart spontaneously. So I used some hotglue to glue the atoms together.
Oh and sorry for the clickbait title - I couldn't resist :-)
