I've been on the fence about 3D printing for years. Not because I thought it was useless, but because I wasn't convinced I'd get enough repeat value out of it to justify the space, the cost, and the learning curve. That changed the moment I bought a Bambu Lab P2S, and it changed again once I discovered the self-hosted Manyfold application.
This is my first real step into self-hosting for 3D printing. I don't have LAN-only control enabled on my printer yet, and I'm very aware that Bambu's cloud-first approach is controversial. But even at this early stage, Manyfold has already become one of the best self-hosted applications I run, and I say that as someone who self-hosts everything from media servers to home automation to custom dashboards.
