1/160th 80' girder bridge

Hey all. I found this ( https://www.thingiverse.com/thing:5604930) design on thinaverse and printed 4 of these at a time on an Elegoo Saturn S 4k printer. I'm using Elegoo standard grey resin. The slicing program is Chitubox. I used the auto support feature. Overall they printed well but the bottom edges are not quite straight. They lifted a bit on the ends from supports attached to the build plate.

Looking for a little help and guidance on how to get this to print correctly.

How big a brim did you use? I tend to use 8 as a default.

For something like that if a brim doesn't hold it down, I'd try adding Mickey-mouse ears at each corner, 10mm diameter and 1mm thick, to anchor them to the bed.
