Don't modify the STL to separate the visors with cylinders. The rest of the part is unsupported, so this will give you lots of support structures or, if omitted, a gigant spaghetti print.

Josef Prusa is already printing stacked visors on his print farm overnight.

I would stack the models of a set of visors in my slicer and for each visor added after the first disable "dropping print to the build plate" and position each consecutive visor one layer height (e.g. 0.2 mm) higher than the last layer of the previous, this way you use the previous visor as a raft for the next.

Below, a reference of someone who prints 8 parts stacked (4 high) overnight:

I wanted to be able to print more than just 2 at a time. Specially over the night when everyone is sleeping. I came up with the idea to stack them on top of each other. Instead of 2 you could print 8 during night. If your printer has smaller build plate and you can only print one its also big help for you.

 

After printing jsut simply peel them away and they will break loose.

 

Gap between parts is 0.3 mm .
