I run this on the home server w/ caddy-tailscale, and I can slice/print from anywhere with a nice easily rememberable domain name. I run a P1S in LAN mode and have it firewalled from actual internet access.

Probably this one: https://github.com/greghesp/ha-bambulab

It's excellent for monitoring and setting up automations around printer events, I use it all the time too.

2nd this, I have my X1C blocked on any inet access, LAN only, it’s a very nice piece of hardware with questionable software :/

The Bambu Labs mobile app doesn't work with LAN mode. I found this app for Android, "LanBu" which does a decent enough job. It's still in beta and wants to display ads. So far my PiHole has blocked all its ads so it's tolerable. I wouldn't mind paying for it, if it's a one-time free and it allowed access from outside my LAN.
