The original propeller launcher is a feat of engineering, and one of the nicest 3D prints you can bestow upon your printer. 

However as stated by the author, it is often prudent to loosen the gears with a drill or driver:

"What can I do if it doesn't turn smoothly even though I added lubricant?

First check if all Gear Axles and Planetary Carriers are inserted all the way vertically. Sometimes it requires a lot of force to push them all the way in. If the issue still persists, check the teeth of the gears for any print imperfections and remove them. You can also use a power drill to spin the output shaft for a couple minutes to smoothen the flanges."

For this reason I created an adapter to help with this operation. If you have a standard chuck driver, you can likely just clamp onto the original fitting without the end cap. Provided your chuck doesn't damage the plastic, but in any case, this is likely a neater solution.
 

Ensure you print it as-is, and then remove the very minor support. Don't print it end-up, it wouldn't require the support then, but it won't have the same structural integrity for high speed spinning.

I hope this helps someone else get their launchers going strong.
