Print Fail Fix Card
For the 3D printing hobbyist whose print just failed at midnight and who is one tab away from posting a photo to r/FixMyPrint hoping someone diagnoses it before morning. Tell the tool the printer, slicer, filament, the failure symptom and whatever settings you remember, and one structured pass returns a ranked diagnosis card: two or three ranked candidate causes with per-cause settings-delta tables in your slicer's dialect, a one-line physical-inspection step, a short test-print recipe with a time estimate, an assumptions receipt list for every blank field, and a one-line closing message that routes you when the failure is actually a resin print, a structural part, or a thermal-runaway signature.
