This purchase includes one online support session of up to 60 minutes. Use it for printer setup, slicer settings, calibration, first layer, extrusion, bed leveling, or common print failures on FDM machines such as Bambu Lab, Prusa, and Creality. Access lasts 7 days so you can book and complete the session. This is a single session. It is not unlimited support, lifetime support, or a guarantee that every issue can be fixed. STL files are sold separately and are not included.
