BMG Clone Components Kit

BMG-style clone internals kit for rebuilding or assembling a dual-drive 1.75 mm extruder. This is the hardware/guts kit: drive gears, shafts, needle bearings, thumb-screw tension hardware, spring, ball bearings, and the large reduction gear/shaft assembly shown in the product photo.

Why use this kit

• All the small BMG-style internals in one bag: useful when a printed extruder project needs the mechanical bits but not another molded extruder body.
• Dual-drive format: BMG-style extruders use opposed filament drive gears for stronger filament grip than a single hobbed gear setup.
• Clone/value part: priced for practical rebuilds, spares, and community extruders where original Bondtech OEM internals are not required.

Specifications and contents

• Product family: BMG-style / Bondtech-style extruder internals for 1.75 mm filament builds.
• Visible kit contents: dual-drive gears, main reduction gear/shaft assembly, motor pinion gear, 3 mm shafts, needle bearings, thumb screw, compression spring, washer/retainer, and small ball bearings.
• Fit context: BMG-style printed or molded extruders, Voron/Clockwork-style rebuilds, Sherpa/Mini-style builds, and other community extruders that call for BMG internals.
• Brand/source: Two Trees BMG-style clone component kit; not an official Bondtech OEM kit.

For individual service parts, see the BMG Clone Extruder Gears, BMG Style Needle Bearings, and Extruder Thumb Screw. If you want the higher-end complete option, compare against the Runice BMG Components Kit - Complete.

Gotchas

• This is not a complete extruder: no printed/molded housing, stepper motor, hotend, fan, wiring, or fastener kit is included unless shown.
• This is a clone component kit, not Bondtech-branded OEM internals.
• BMG-style community designs vary. Confirm the shafts/gears your printed extruder calls for before ordering.
