This hardware accessory for your MakerBot Replicator 2 Desktop 3D Printer helps keep MakerBot PLA Filament flowing more reliably, without the need for occasional adjustments. Inspired by designs uploaded to Thingiverse.com by such users aswhpthomas, emmett, and whosawhatsis, the spring-loaded arm presses a bearing against the filament, providing a constant amount of pressure on the gear that drives the plastic through the nozzle. The installation is simple. Take a look at the written instructions and video guide below to get a feel for the process. Made of industrial-grade, injection-molded plastic and durable hardware.
The serial number is located on a sticker on the bottom of your Replicator 2 Desktop 3D Printer.
Your Extruder Upgrade will ship within 6 weeks. Shipping and handling is not included.
