Rear Top Plate (Fan) for Flashforge GUIDER3+ — Replacement Part MPN 70002170003

Replacement rear top plate with integrated fan designed for the Flashforge GUIDER3+ chassis. This OEM-style part restores the enclosure's upper ventilation and airflow path, helping maintain stable internal temperatures and remove fumes or heat generated during printing. It is intended as a direct-fit replacement when the original rear top plate or fan assembly is damaged, noisy, or no longer performing as required.

Advantages

The rear top plate includes a pre-mounted cooling fan and housing shaped to match the GUIDER3+ enclosure, enabling straightforward installation and reliable airflow. Using a dedicated replacement part preserves the printer's original ventilation layout, reduces thermal variation inside the build chamber, and can decrease resin or filament fumes accumulation. The component is designed to meet the mechanical fit and airflow demands of the GUIDER3+ without extensive modification.

Suitable for

• Repairing a damaged or cracked rear top plate on the GUIDER3+
• Replacing a worn or noisy exhaust fan to restore proper ventilation
• Preventive maintenance to maintain consistent enclosure airflow
• Restoring proper cooling after modifications or accidental impact

Key specifications

• Form factor: rear top plate with integrated axial cooling fan and mounting points compatible with GUIDER3+ chassis
• Material: molded plastic housing designed for enclosure mounting and heat resistance typical of printer top panels
• Function: replaces exhaust/ventilation at the rear upper section of the build enclosure to maintain airflow
• Compatibility: designed to fit GUIDER3+ enclosure geometry and mounting arrangement
• Electrical: fan powered by the printer's existing fan connector and wiring harness (matches original fan electrical interface)

How to use

Power off the printer and disconnect it from the mains before beginning replacement. Remove the damaged top plate by unscrewing the fasteners that secure it to the enclosure and gently disconnect the fan power connector from the printer wiring harness. Align the replacement rear top plate with the enclosure mounting points, connect the fan power connector, and secure the plate with the original fasteners. After reassembly, power on the printer and confirm that the fan operates and that airflow through the enclosure is restored. Verify there are no unusual noises or vibrations and that all mounting points are secure.

Usage recommendations

Use this replacement part with the original GUIDER3+ fan power connector and mounting screws. Inspect wiring and fan operation after installation, and avoid forcing the housing into place to prevent stress on mounting tabs. If you notice persistent vibration or abnormal noise, stop the printer and recheck mounting and connector seating; replace the fan if necessary.
