BondTech Extruder Upgrade Kit for the MakerBot Replicator 2

This Makerbot Replicator 2 extruder upgrade kit replaces the original feeder and coldblock.

It allows for more reliable printing with all types of filaments, both rigid and flexible, and the DualDrive system ensures that the extruder never loses its grip on the filament, making grinding and slipping a thing of the past.

The original motor is used and the PTFE tube is reliably held in position with a 6mm industrial push-fit connector.

Installed in about half an hour with standard tools.

This block has a M6x1.0 thread through the coldblock for the factory heatbreak.

In the factory setting, there is a low-height nut both above and below the cold block. In this configuration, the upper nut must be removed.
