I added a printhead for the Volcano variant of E3DV6. It is a simple extension of the part cooling ducts from the original Voron Stealthburner E3DV6 printhead.
Not the nicest looking mod unfortunately, my cad abilities are limited :/
(This should also work with the CHC Pro hotend.)

The author remixed this model.
