This purchase includes one online support session of up to 60 minutes. Use it for 3D printer setup, slicer settings, calibration, first layer, bed leveling, extrusion, print quality, or common print failures. Support is delivered through Whop chat or video as scheduled after purchase. Access is available for 7 days so you can buy, reach out, book, and complete the session. This is not unlimited support, not a lifetime promise, and not billed by the minute. This product does not include STL files.
