Tevo Tornado, CR-10, and clones: Dual Front Facing Extruders

thingiverse

This is a remix of my previous work that supported only one extruder. This design supports two extruders side-by-side. I designed the mount to bring the extruder to the front of the X-axis, facing the user, so that they will be easier to access with the printer inside an enclosure. The mount is designed to be installed on the spacers holding the X-axis stop switch. As the four screws holding the cover are very short, four longer M3 screws are required for a good grip. I tested the print with both PLA and PETG, both at 50% infill, with three wall/top/bottom layers. They both work fine but the PETG tends to be a bit more flexible, meaning that it flexes a little but also absorbs a bit of the vibrations caused by the extruders, quieting down the printer a bit. Make sure to rotate it so that the large surface is on the bed.
