Geeetech I3 E3D V6 extruder

thingiverse

Some years back when I entered the 3D printing world, I purchased a Geeetech I3 Pro C which came equipped with a double MK8 hotend. My initial goal was to have a nozzle in 0.4mm and another in 0.2mm for enhanced precision. However, I quickly discovered that the MK8 hotend is unreliable (I encountered a lot of clogging), and also found it nearly impossible to adjust two nozzles at once. So I swiftly replaced the double setup with a single E3DV6 of my own, which features a support for a BLTouch. Nevertheless, the default fan supplied with an E3DV6 is too small and not efficient enough in my opinion. Thus, recently I designed a new extruder, again tailored for the E3DV6. It's still utilizing the original MK8 extruder plus the original Geeetech fan but located on the left, blowing the heatsink through a tunnel. It incorporates a BL Touch for auto-levelling and another blower fan to cool down the print area. The Z position of the BL Touch is adjustable. Parts are printed in ABS, but PETG should also work well. Do not use PLA as it will not withstand heat and mechanical stress. Use the screws and square nuts provided with the printer for assembly. The fan duct has to be glued onto the fan support (use cyanoacrylate). Eventually, the printer firmware must be updated to add BL touch support. Offset between the probe and nozzle is X=29mm and Y=0. Don't forget to adjust your hotend PID settings. Even though it's not perfect, I hope this design will prove helpful to those struggling with this printer.
