[Chimera-users] how to generate good STL code for atoms display

Dear chimeras,

Does anybody know of a good way to generate lean STL code for atom/bond display?

Take this example. I'm generating STLs to 3D print GFP. Exporting the
ribbon of the beta barrel generates an ok STL of 6.8MB. However,
exporting the wire atom display of the chromophore generates a
horribly inflated STL of 13.7MB - almost twice the ribbons file
despite the tiny size (see screenshot attached). Printing the
chromophore is problematic since it contains a lot of weird internal
structures instead of being a clean surface model of the wireframe. A
netfabb repair of the chromophore STL

Looking forward to your expert ideas.

All the best,
