While not every hot end has the same position on all your Anet A8 3D printers out there, I developped a flexible cooling nozzle. This flexible cooling nozzle can be adjusted perfectly to any position of the hot end of your 3D printer.
Print this in the direction as shown in the STL file. In that case you do not need supports. I only recommend a brim to fix the parts steady on the printer bed. I printed the parts with 100% infill. It does not take long to print, approx. 20 minutes per part.
When puting the parts together, I recommend to heat up the nozzle a bit to fix it on the ball joint without problems.
Have fun with this perfect cooling nozzle!
