Geeetech I3 A Pro: E3D V6 + Titan + Cooling

**UPDATE 05.2020** Uploaded a 20 tooth deflection pulley to replace the old ones and reduce ghosting. You need 4 x "MR93 W2.5" bearings. **UPDATE 02.2020** Did a complete overhaul to my previous version. I decided to use the original mounting-plate to install the x-carriage. No more need to disassemble the hole x-axis and the original belt-holder can be used too. Also adopted the „prusa bear cooling fan“ to my version.  ASSEMBLING COMING SOON!  As you can see on the picture, I installed "MaazaFin's Smooth X-axis". It is not necessary when you want to use my extruder-mount but I would recommend it. The orignal X-axis causes the Z-rods to bend, when tensioning your extruder belt. You can find it here: https://www.thingiverse.com/thing:1103976 Please do **not** use flexible couplers for your z-axis like this:  They behave like a spring when your steppermotors are going to move your x-axis up. Especially when you can not ensure that your x-axis is absolutely horizontal. Therefore your couplers will absorb torque from your steppermotors and can cause tilting in your x-axis. **UPDATE 07.2019** I was not really happy with the mount for the 3D-Touch. The space between nema-motor and 3D-Touch was too small. Very flat screws were needed to install the sensor. With the new version you can use normal m3 screws.  **UPDATE 06.2019** I created a new fan made of four parts instead of only one. Here are the reasons why: - Printing the fan (in one piece) with materials with less good bridging behavior like PETG is quite hard. I wanted the reduce the influence of a rough surface on the airflow. - Decided to adopt the "prusa bear fan bracket". With this, printing the hole cooling-fan in one piece is not really practical.  - By deviding it into four parts its much easier to print cause of the lesser printheight and the new alignment. - I also made all parts a bit thicker, so the fan isn't that fragile as before and the parts are easier to glue. **Credits:** First of all I have to say thx to "bliatun" for his great design and sharing his idea. His extruder mount is compact and easy to assemble. So I decided to adjust it to my "Geeetech I3 A Pro". **Goals to achieve:** - Get rid of that heavy MK8 extuder + stepper motor and safe weight - Gain more printquality by installing a E3D-V6 and have the possibility to cool filament - A wider range of useable printmaterials by installing a Titan extruder - Use a probe (BL-Touch) without printing an extra mount. **Notes:** - Please check alignment of the printed parts in your slicer software. - If possible print "Part 4" (nozzle cooling) in ABS - cause its close to the heaterblock. - If you are using the "17HS10-0704S" stepper motor, you have to switch the Connection wires (red + green) as shown in the picture!  - Also lower your voltage at your stepper driver to 0.5 volts. Thats enough for the pancake motor. - If possible use Loctite Super Glue 3, perfect for glueing PLA or PETG - Dont forget to recalibrate your esteps for your new extruder and check if you have enough tension between filament and the extruder gear.
