This purchase includes one online support session of up to 60 minutes. Use it for printer setup, slicer settings, bed leveling, first-layer issues, extrusion, and common print failures on desktop FDM machines. Access lasts 7 days so you can book and complete the session. This is not a guarantee that every issue can be fixed, and it is not lifetime or unlimited support. STL files are not included. The Desk Essentials STL Pack and Hex Planter are sold separately.
