YINGHUA Extruder Back Support Plate with Pulley for Ender 3 3D printers accessory

SKU CH-YTD0-6EYEH

A metal extruder back support plate with an integrated pulley designed for the Ender 3 3D printer

  • Durable metal construction resists wear and high temperatures
  • Oxidation-treated surface ensures stable sliding and long service life
  • Accurate hole positions guarantee precise fit on Ender 3 extruders
  • Adjustable tension allows fine-tuning of filament feed pressure
  • Complete kit includes back plate and pulley for straightforward installation

Ender 3 extruder back support plate

The YINGHUA metal back plate mounts on the rear of the Ender 3 extruder assembly to reinforce the frame and keep the filament path aligned. It is aimed at owners who want a sturdier replacement for the stock plastic part or who are upgrading to a direct-drive setup that puts more load on the extruder body. The kit includes the plate and mounting hardware but does not supply an extruder motor or gear set.

Metal plate with optional pulley adds rigidity

The plate is machined from metal with oxidation-treated surfaces that resist heat and wear while keeping the filament channel sliding smoothly. An optional integrated pulley lets you guide the filament with adjustable tension, reducing drag during fast prints. Hole positions match the Ender 3 mounting pattern, so installation only requires the original screws and a few minutes of assembly time.

Direct replacement for Ender 3 plastic back plate

The part fits the standard Ender 3 extruder mounting holes and works with the factory Bowden connector or common direct-drive adapters that share the same bolt pattern. It will not suit printers with different extruder spacing, dual-gear housings that need wider clearance, or any non-Creality machines unless their hole pattern happens to match. Buyers needing a complete extruder unit or a different mounting standard should look elsewhere.

Questions about this item

Will this back support plate fit the original Ender 3 extruder assembly I already own?

Yes, it is designed specifically for the Ender 3 and installs directly onto the existing extruder backplane using the stock mounting pattern.

How can I verify the pulley is sliding correctly after I mount the plate?

After installation, manually rotate the pulley; it should spin freely without binding, and the adjustable tightness feature lets you dial in smooth, stable filament feeding.

Does the kit come with a new extruder body or just the back plate and pulley?

The package includes only the back support plate kit with pulley; the extruder body itself is not included and must be supplied separately.
