Custom heater block to fit E3D nozzle on Ultimaker 2 ("The Olsson Block") in Modifications, third party add-ons & other hardware Posted March 22, 2015 Olsson makes prints with 0.8,mm Nozzle that looks almost like mold injected. Mr Olsson; Could you share a photo of the white ring, and the settings? Nix! ..... :-P :-P :-P :-P :-P :-P I'd like to see a part that looks like mold injected. However I will also try to print with 0,4 or 0,5.
