Preparing Chain Link STL

how should I print this part? would you recommend that I print flat on the build platform, or angled with supports? interestingly I get red shading when I rotate the part. should I be concerned about that?

Can you share a few more angles of the model? It’s a bit hard to see what’s going on currently.

here is the model. it came from thingiverse
