Tris(2,4-di-tert-butylphenyl) phosphite, C42H63O3P, is a big molecule with 109 atoms: 42 carbons, 63 hydrogens, 3 oxygens and one phosphorus in the middle.
The phosphorus sits in a phosphite ester group, P(O-C)3, and each of its three oxygens holds a benzene ring. Every ring carries two tert-butyl groups, so the three arms look alike. There are 111 bonds in total, 93 single and 18 aromatic.
This is a ball-and-stick print where each sphere has its element symbol engraved into the surface, so the phosphorus, oxygens, carbons and hydrogens are easy to tell apart without painting. It is a large model, so give it a roomy bed.
Scale it up in your slicer before printing. Plain PLA on an FDM printer works fine, and a fine layer height keeps the engraved letters sharp.
