That's right, the stealth helicopter.

With (Wait for it...) ROTATING ROTOR!!
(Tail rotor does not rotate...)

Read directions for accurate print!

UPDATE: The original "Parts" file has now been replaced with a repaired file. It should slice properly now...

I printed mine with a .35mm nozzle and 3mm filament.

As you may notice, in the "parts" file there is a rear rotor blade. This is because when I sliced the halves of the chopper, the blade did not slice. (If yours does, great. If not, glue in the rotor as I did)

This model should print perfectly without any support material!

You may nead to widen or clear the rotor cavity for a good spin. Hold the two halves together with rotor in place to get an accurate idea of how well your rotor WILL spin before glueing!

That way you can make any neccessary adjustments...
