This purchase includes one online support session of up to 60 minutes. We will work through 3D printer setup, slicer settings, calibration, first layer, print quality, extrusion, bed leveling, or common print failures over chat or video. Access lasts 7 days so you can book and complete the session. This is one timed session, not unlimited support, and it does not guarantee every issue can be fixed. STL files are sold separately.
