[Chimera-users] Help needed urgently

Dear Clare,
It is recommended to use the “struts” command on your structure in Chimera to strengthen it before exporting as STL.  As you have seen, the usual display ribbons alone are generally too flimsy for 3D printing.  This command has a few options.  By default, it fattens up the ribbons and adds strengthening rods.

Example commands in Chimera:
open 1yvx
struts @ca

(…then export as STL)

We don’t have tools in Chimera for editing the STL after it has been created, sorry.
I hope this helps,
Elaine C. Meng, Ph.D.
