Import the PDB Structure into UCSF Chimera and customize its appearance (see tutorials Visualizing Structures with UCSF Chimera for Beginners and Protein Visualization with UCSF Chimera ).
Sample workflows for creating files for 3D printing: Read an overview of the pros and cons of different 3D printing file formats at all3dp. If your molecular viewer can export any of these file formats, you can create print-ready models. stl file format is the most common standard for 3D printing and is supported by most single and dual extrusion printers. This collection of files can be downloaded to create curated 3D models for education.
