# Henry Rzepa's [https://wiki.ch.ic.ac.uk/wiki/index.php?title=Mod:3D hints]. We have 3D printed about 30 models in full colour (the material is gypsum + inkjet) and there the secret is to adjust the bond radius to ensure that the resulting model is reasonably robust. Despite such precautions, the models do tend to be fragile. This site also has instructions on how to scale the model (we adjust the scale to produce models of about 10-15cm in size, or ~£60) and how to produce surfaces (molecular and NBO orbitals for example). Also not found in standard coordinate databases are computed transition state models, which are useful for inspecting eg steric clashes/attractions which may determine reaction outcomes. | # Henry Rzepa's [https://wiki.ch.ic.ac.uk/wiki/index.php?title=Mod:3D hints].

File repositories for 3D models
NIH 3D Print Exchange
Target audience and data is for biomedical applications (e.g., anatomy, labware, protein and macromolecular structures, bacteria, cells).
Searchable by names and phrases. This seems to work well for the target data.
RSC Crystal Data Repository
http://api.beta.rsc-us.org/Crystals/v1/cod/
One of four planned new RSC repositories (crystals, compounds, reactions, and spectra). Currently contains:
- The entire Crystallography Open Database (COD) of 289 395 .cif and 48 022 .hkl files of molecules and extended solids;
- 3D Printable Files: 31 239 .wrl files (color printing) and 11 732 .stl files
Still in beta mode, you can manually browse through files. Repository will soon have a user interface that is fully searchable (name, structure, formula, SMILES, InChI, and others) with deposition and crowd-source curation/annotation platform.
3D printing services
Print on demand from the file (e.g. 
.wrl exported from Jmol) that you upload.
