Just in case someone needs a 3d model of the E3D v6 Hotend… you can grab the 1,75mm universal version in a not so detailled version at GrabCAD. Just did a quick drawing this morning as i need it for some mount construction work.
File currently only available in F3D format (Fusion360) and it’s also in their gallery including some more renderings here https://fusion360.autodesk.com/projects/e3d-v6-hotend-1-75mm-universal. You can of course use Fusion360 to export to any format of your choice (it does quite a lot)
Dimensions should be fine but i’ve not yet modeled the fan mount and didn’t do screws, thermistor and heater.
