BMG Clone Components Kit
Couldn't load pickup availability
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.

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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
