Product variants

Quantity

Two Trees BMG clone internals plus the fittings, collets, extruder liner and tube that complete the filament path. One bag for a BMG-style extruder rebuild or a new toolhead.

What's in the kit

1× Two Trees BMG clone internals kit — stainless dual-drive gears, white 50T reduction gear, shafts, needle bearings, spring and thumbscrew
1× PC4-M10 push-fit fitting, black collar — the extruder-side coupler for 4 mm tube
2× ECAS04 embedded collet with blue release caps — the toolhead-side tube sockets
2× orange collet clips — lock the tube against back-out
1× PTFE tube, 2 mm ID × 4 mm OD, 300 mm — the extruder liner: cut it to length for the filament path inside the extruder body. Not every extruder uses a liner, but having it in the bag is what makes this a kit.
1× white PTFE tube, 3 mm ID × 4 mm OD, 1.5 m — the feed / reverse-bowden run

Which tube

White PTFE, 3 mm bore × 1.5 m — the loose bore — lowest drag for long runs where slip beats constraint. The liner is always 2 mm.
Other bores: 2 mm or 2.5 mm; or the same kit with clear FEP or black PTFE.

Fits

Any BMG-style dual-drive extruder body — Voron Clockwork, Afterburner and Mini Afterburner builds and the many printed BMG clones; 1.75 mm filament, 4 mm OD tube.
Abrasives? The same kits with Runice RNC-coated internals.

Gotchas

No extruder housing, motor, hotend or fasteners — this is the internals and the filament path.
ECAS04 needs a housing pocket cut for the embedded collet; the PC4-M10 needs an M10 port.
Same parts, same shelf as the singles linked above — if the kit reads sold out, one of its parts is.

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 returned, I will not be responsible for returning 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.
