I’m definitely not a printing expert but it looks like you’re under extruding, is the extruder the same size as the old one or is there some other change like that? I say this because the bottom layers look better than the higher ones, from memory cura over extrudes for the first few layers to help with bed adhesion.
For anyone reading this best practice is to put it behind a VPN or something similar, I personally have it setup as a subdomain (bitwarden.domain.com) using nginx proxy manager to sign using let’s encrypt.
In saying that I’m in the middle of migrating everything to swag (which is pure nginx with fail2ban built in) just to make management of some other things easier.
I will say if you do set it up public facing, make sure you disable signups for both security and to stop random people from using your server.
