Dual Bowden E3D Extruder - printrbot plus v2

thingiverse

This is a custom carriage designed specifically for the Printrbot Plus v2. It accommodates two bowden e3d extruders, features fans mounted on both the fins and nozzles, all seamlessly integrated with the printer's rails. Key components include high-performance 40mm fans, precision M3 screws, 6-32 screws (a total of seven are required), a single nut for securing these fasteners in place, and robust LM8UU linear bearings that ensure smooth operation. The carriage is divided into four sections, each of which can be printed independently without the need for support material – except for the rail clamp piece, which may require some creative problem-solving to avoid printing supports. Printing Requirements To bring this design to life, use a PLA filament heated to 205 degrees Celsius. Optimize print settings with a layer thickness of 0.2mm and 25% infill. This will result in a robust yet precision-crafted carriage that is ideal for the Printrbot Plus v2.
