70 mm EDF nacelle

~~This is just the nacelle , you will have to provide the support structure for the fan and blast tube.
The nose ring fits over the fan case and is made with thick enough plastic to support the rest of the nacelle.  I designed it so the fan is close to the front to use the length some will need to  put the ESC behind the motor this also keeps the inlet plastic thick.  The nacelle sides are formed long enough to reach all the way to the edge of the inlet ring for additional strength.
 At the tail end, the exhaust diameter is reduced from 70mm so you can make the blast tube tapered for efficiency. If your fan requires no taper, removing plastic from the aft end will enlarge the exit hole.
