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. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/struts.html> Example commands in Chimera: open 1yvx ~display 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 ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco

Hello there, I have just sent this file to a 3D printers and sadly it has disintegrated when post printed and the model has been bathed and washed.
Attached is the link to the STL. file https://www.dropbox.com/sh/2nytyw6989h0v2l/AADiXrhb8mUfi53J95co-Bvja?dl=0
I was wondering how I could perhaps make the structure 3D print safe. Would you be able to help me join the bonds and also make them a lot thicker?
Any help would be most appreciated as this is meant to be in an exhibition come Friday.
Best Wishes,
