MolMol is a Blender add-on for scientific molecular 3D modeling using the classic colored-sphere-and-stick representation style. It builds publication-ready molecular structures and includes automatic bond detection via the Atomic Simulation Environment (ASE), customizable atom geometries, and advanced rendering options.

The tool allows you to import or build molecules and uses ASE to infer bonds from atomic coordinates, supporting PDB and CIF formats. You can reference external Blender libraries with sp³, sp², sp, bent, and other hybridization geometries. Bond radius, gap distance, and hydrogen handling can be customized. MolMol also supports batch processing for importing and processing multiple structures in a single workflow.
