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