This purchase includes one online support session of up to 60 minutes. Use it for 3D printer setup, slicer settings, bed leveling, first layer, extrusion, calibration, print quality, or common print failures. Sessions are scheduled after purchase and delivered by chat or video. Access lasts 7 days so you have time to book and complete the session. This is not unlimited support, not a lifetime promise, and not bundled with STL file downloads.
