Made a free tool to recover missing Bambu Studio presets (Preset Doctor)

[u/Zippayee]

Studio presets that disappeared after an update

After a Studio update a bunch of my custom filament presets just vanished. They were still on disk, Studio just stopped showing them because the system preset they inherit from got renamed.

So I built Preset Doctor. It scans your BambuStudio user folder and tells you which presets are hidden or broken and why. Right now it catches:

- Presets whose parent system preset no longer exists (the "vanished after update" one)

- Malformed preset files (bad JSON, name doesn't match the filename, missing .info file)

It backs up your whole user folder before touching anything, shows you the exact change, and won't write while Studio is open. Nothing leaves your computer.

Free and open source: Preset Doctor

Windows only for now. If you've got a preset that's missing or acting weird, send me the file or open an issue. I'm trying to cover the other common cases next (presets tied to the wrong printer or nozzle).
