Its all about the right retract settings (and good quality filament)! On the Ender 2 with the stock bowden Extruder my best retract settings for this hard to print object are:
8 mm at 100 mm/s, combing for all, minimum extracted filament 0mm, minimum travel 0.5 mm (cura 15 - the newer versions just confuse me and never got better results!)
