Bondtech Wanhao I3 Extruder Upgrade Kit
This kit provides a high-performance material feeding system with the ability to print faster with improved quality. The adjustable thumbscrew allows you to fine-tune the force acting on the filament. With quick-release lever you can load and unload filament with ease. The original metal plate that holds the extruder needs to be modified in order to give room for the extruder, this is easily done with a hacksaw and a file.
