This mount is compatible with the genuine E3D v6, Aero and BLTouch. It's designed to be easy to print and install.
The stock stepper motor for the FT5 has been used, although you could create a spacer and use a pancake stepper instead.
The layer fan is a 40mm x 20mm or a 40mm x 10mm.
The mount also allows the full printing area 300x300x400.
I'm still working on the fan duct but extra holes have been added to the mount to make sure it's compatible with new iterations.
