Replicator 1 Upgraded Drive Block - Left

Use these parts to assemble the Spring-loaded Drive Block alternative to your MakerBot Replicator 1 extruder. Includes the injection molded parts as well as the metal hardware designed to fit the left extruder on a Replicator Dual. 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!
