Replicator 2 Upgraded Drive Block/ Replicator 1 - Right

Use these parts to assemble the Spring-loaded Drive Block alternative to your MakerBot Replicator 1 or Replicator 2 extruder. Includes the injection molded parts as well as the metal hardware designed to fit the Replicator 2 and the Replicator 1 - Right side. The Spring-loaded Drive Block is a simple system for pressing the filament against the drive gear using a constant amount of force. We salute the innovative Thingiverse users who worked collaboratively on this design over time!
