Drone keychain

I recently bought a DJI Phantom 3 Standard. I really love this drone and wanted something to let people know I'm a drone pilot (and a 3D 'designer') :-). I decided to create a keychain, which I can show people.

I created this in OpenSCAD and made it a print-in-place with rotating propellers (why else have a 3D printer but to print something that is hard :-) ).
My printer is not that accurate, so I made the airgap (between the propellers and the body) .5 mm. Feel free to edit the OpenSCAD file and reduce the airgap (it is a parameter, so it should take less then a minute).

Enjoy and let me know (and see) when you print this.

Make sure to use the 2016 version of OpenScad!
