Dual Extruder Mount for e3dv6

thingiverse

Since I was unable to locate a suitable dual-extrusion carriage, I decided to create one that met my requirements. The carriage is designed to hold two E3Dv6 bowden hotends. To cool them, I chose to use a single 40mm fan. The second hotend can be moved vertically for approximately 1.6mm to facilitate nozzle levelling. To accomplish this, simply remove the front fan and loosen the center screw slightly. If the screw is over-tightened, the hotend will no longer move. This carriage is designed to utilize RJ4JP-01-08 drylin bearings and a radial fan for material cooling. If you choose not to use the cable chain adapter, you can install the "filling" mechanism, which ensures stability. When printing, supports are required for the "Extruder Mount front" and "cable chain Adapter". To build this carriage, you will need: 4 x RJ4JP-01-08 drylin bearings 7 x M3x25mm screws (for carriage) 1 x M3x30mm screw (for carriage) 1 x M325mm screw (for extruder mount) 9 x M3 nuts 4 x M3x20mm screws (for front fan) 2 x M4x20 screws (for rear fan) 1 x 40x6mm fan 1 x radial fan, 40mm in diameter (the original stock fan from Anet A8) And of course, two E3Dv6 hotends. All parts are precision-cut and designed to fit snugly together. It is essential to ensure that the front fan operates when the extruder is heated, as failure to do so may result in deformation of the mount. I personally wasted two mounts during the setup process for dual extrusion, which is why I stress this point. I have not yet designed a nozzle for material cooling; however, feel free to create one and share your design with me.
