This purchase includes one online support session of up to 60 minutes. We work through 3D printer setup, slicing, calibration, first layer, extrusion, bed leveling, print quality, or common print failures over chat or video. Access lasts 7 days so you can buy, reach out, schedule, and complete the session. This is not unlimited support, not a lifetime promise, and not a guarantee that every issue can be fixed. STL files are sold separately.
