"Fixed" Darth Vader Shroud

The original shroud did not print well on my delta printer. All other files were GREAT. This one kept separating the shroud from the emitter. So I dumped it into Sketchup and made a better connection. However, the original and this one are not 100% manifold and for some reason I cannot close them. However, Cura and Simplify3D slice them just fine. Slicer on the other had chokes on them. I have include the STL as I printed it on a FLUX 3D Delta, the Sketchup file if you wish to see it or mod it,
