I did this modification of Foehnsturms amazing modular printhead (https://youmagine.com/designs/ulitimaker-orig-modular-printhead-merlin-ubis) using the measurements needed to attach an E3D V6 hotend, since It is the hotend I am using now for my 2 Ultimaker Originals. foehnsturme3dv6b ist the counterpart to foehsturme3dv6c, be sure to print both. My settings were 3 shells and 20% infill using a 0.6 mm nozzle. Have Fun !
