Hi David,

Chimera friends, please forgive me for stepping in here.

Chimera is a terrific tool for preparing proteins for 3D printing. In
fact, we use it at the NIH 3D Print Exchange to transform PDB and other
files into 3D-printable objects. Although I'm sure that Elaine or others
could give you some great advice about how to do this yourself in Chimera,
I would also like to invite you to try the NIH 3D Print Exchange. Once you
register (for free) you can use our "Create" tools to upload the PDB file
of your trimer and get several different representations of your protein
suitable for 3D printing, including a ribbon representation with the
individual ribbons joined.

If our automated tools are not sufficient for your purposes, I would be
happy to share a few hints with you. For starters, I think the tool you
want is called "struts" in Chimera:

Hope that helps,
