Runice BMG Components Kit - Complete

Runice BMG-style extruder component kit for rebuilding or assembling the mechanical internals used in Voron Afterburner, Mini Afterburner, and other BMG-style 1.75 mm direct-drive extruders.

Why use this kit

• Runice-machined BMG-style internals in one complete hardware kit: gears, shafts, bearings, tension hardware, and retaining clips.
• Useful when your printed or machined extruder body is already handled and you need the metal guts rather than a full molded extruder.
• Standard silver gear version; choose the RNC-coated Runice BMG kit instead if you want the abrasive-filament wear upgrade.

Check before ordering

• This is not a complete assembled extruder: no printed/molded housing, motor, hotend, fan, wiring, or toolhead parts are included.
• This is a Runice BMG-style clone component kit, not genuine Bondtech OEM internals.
• Confirm your extruder design calls for BMG-style internals before buying.
