Printrbot 1405 External Extruder

thingiverse

This component enables users to move the extruder away from the print head, significantly reducing the weight of the printhead and subsequently improving print quality, especially on printers that undergo rapid direction changes. By incorporating this upgrade, the weight burden of the printhead is diminished, yielding superior print results, thanks to a considerable reduction in wear and tear on delicate mechanisms. Instructions are outlined below: Three distinct components comprise this installation process: The first involves replacing the existing extruder mounted on the print head Next, install a new mounting system for tubing onto the printerbot's extruder assembly Thirdly, optionally integrate a 40mm fan attachment, carefully placed to cool the upper section of the hot-end during long print operations. Test results confirm that even lengthy prints exceeding eight hours can be achieved with flawless success without this feature. An empty piece of pressured-air tubing was cleverly repurposed as the conduit linking the extruder to the hotend Carefully drill out a portion of the entire setup for improved accessibility A well-designed locking mechanism secured in place by M3 screws and matching nuts guaranteed reliability throughout the assembly process Additionally, an essential tip emerged from hands-on experience - ensuring smooth operation necessitates the application of lubricating oil along the inner walls of the tubing, which may otherwise create unacceptable friction levels impacting motor performance.
