This purchase includes one online support session of up to 60 minutes. We can work through 3D printer setup, slicer settings, calibration, first layer, bed leveling, extrusion, print quality, and 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 a guarantee that every issue can be fixed, and it is not unlimited or ongoing support. STL files are sold separately.
