This is my latest version, which uses the stock 40mm fan for more airflow and easier-to-find replacements. Work in progress because I have not had time to test it extensively but the basic premise of the design is the same as my other one, which has been holding up well. This design does not require the plate to be trimmed, however you will require 2x M3 x 25mm and 2x M3 x ~10mm screws, available at any hobby shop or many places online. Use at your own risk - I am not responsible for any injury or damage, etc. Print in ABS, use supports and 100% infill. Finish by drilling out the 3mm holes, which are intentionally sized a bit small to accommodate variations in tolerances. File a notch into the plastic part that mounts to the extruder. You will see where you have to file when you go to test fit - just file where the top of the e3d would hit the plastic. I decided this was better than spacing the motor up higher than necessary. Finally, cut the PTFE tube at an angle so it fits close to the hobbed bolt and won't let soft filament go anywhere but where it's supposed to. Enjoy!
