Also, the NIHPresets https://cxtoolshed.rbvi.ucsf.edu/apps/chimeraxnihpresets bundle on the toolshed has several presets useful for 3D printing.

Dear François-Hugues Porée, In ChimeraX, there is no GUI tool but you can use the "cartoon style" command to increase ribbon (cartoon) width and thickness to specific angstrom values. For details see the help: https://rbvi.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style

However, ChimeraX also has a "struts" command that will automatically increase ribbon thickness in addition to adding some stick pseudobonds specifically to make a 3D model stronger. So you may want to use "struts" instead : https://rbvi.ucsf.edu/chimerax/docs/user/commands/struts.html

Another thing to consider for 3D printing is the number of triangles of the object, which you can adjust with "graphics quality": https://rbvi.ucsf.edu/chimerax/docs/user/commands/graphics.html#quality

For ChimeraX questions in the future, you may want to use the other address chimerax-users@cgl.ucsf.edu (CC'd here) -- since the answers are different for the two programs, we try to not confuse people between them.

I hope this helps, Elaine

Dear Chimera Team, first of all, I would like to thank you for providing a sotfware solution to molecular visualization and by the way 3D-printing.

I send you this message concerning the UCSF Chimera X version. We usually are preparing our 3D-printing files from data collected from the pdb and to ensure the rigidity of the system, we thick the ribbon size and also add some H-bonds (mainly for helices). However, we are not able to find the way to do it in this version. In the previous version (1.17), the command line was : Tools-depiction-ribbon style editor

Could you explain us the new procedure to make this ?

We also noticed that the opportunity to save the file in a stl extension was not allowed in the 1.17 version. This option is running in the X version.

Thank you very much for your reply

Best regards.
