pdb2print: 3D-printable multi-material molecular models from PDB structures

First public release. Converts PDB structures into multi-object 3MF files with one named object per chain, so each chain can take a different filament. Handles DNA and RNA as printable tubes and rungs with the strands welded at each base pair, and can place press-fit magnet pockets automatically where chains meet. Live at pdb2print.org.
