## Summary description

Replacement drive gear for the Prusa Mini and Prusa Mini+ extruder. Designed to mesh with the feeder mechanism, this gear transmits drive motion to filament feeding. Suitable as an OEM spare part (MPN PSA-18653) for repairing or maintaining extrusion performance and consistent filament transport in FDM 3D printers.

## Long description

Replacement drive gear designed for the Prusa Mini and Prusa Mini+ extruder. This gear meshes with the feeder mechanism to transmit rotational motion to the filament path, ensuring steady filament movement and consistent extrusion in FDM 3D printing. It is supplied as an OEM-compatible spare part intended for maintenance and repair of extrusion assemblies on compatible Prusa printers.
Advantages
The gear is engineered to match the geometry of the original extruder drive so it aligns precisely with the feeder and bearing surfaces. Its construction provides reliable tooth engagement to reduce slipping and improve filament grip, supporting stable extrusion rates. Using a direct replacement drive gear helps restore original feeding performance without the need for modifications.
Suitable for
Repairing filament drive assemblies on Prusa Mini and Prusa Mini+ printers
Replacing worn or damaged extruder drive gears to eliminate slipping
Maintaining consistent filament feed for regular FDM printing
Key specifications
Compatible printer models: Prusa Mini, Prusa Mini+
Function: gear for filament drive in extruder assembly
Mounting: designed to align with standard extruder shaft and feeder interface
Material: durable engineering plastic suitable for mechanical wear (manufacturer specified)
Form factor: gear profile and tooth geometry matching OEM drive requirements
How to use
Power off and cool the printer before starting replacement work. Remove the extruder cover or assembly as described in the printer manual, then slide off the old drive gear from the extruder shaft or loosen its retaining fastener. Fit the replacement gear onto the shaft ensuring correct orientation and full engagement with the feeder mechanism and bearing surfaces. Reattach any fasteners and covers, then perform a filament loading procedure and a short extrusion test to confirm proper feed and alignment.
Usage recommendations
Inspect the filament path and pinch/feeder surfaces when replacing the drive gear; replace worn idler bearings or cleaning debris that can affect grip. Use filament with appropriate diameter tolerance and check extruder tension to maintain consistent extrusion. If uneven feeding persists after replacement, consult the printer maintenance guide for further diagnosis.
