Propeller Launcher - skinny dragger

I really like the excellent propeller launcher that Davidcolsson designed, and my kids love it. However, when I printed it, the dragger was too tight. I think that it was due to my print settings adding extra thickness to complete a layer. To counter this, I took .3mm off of the bottom and sides of the dragger. With these dimensions, it printed great at .2 mm layer height.

I highly recommend Davidcolsson's propellor launcher. It is great fun!
