Freewing 90mm outrunner fan center burner mount

This part is used to attach an LED bulb to the aft end of a Freewing 90mm outrunner EDF unit that comes on the Freewing 6 cell F-4 Phantom. All the instructoins for making it are on RCGroups in "Making an inexpensive EDF centerburner" forum. You need to remove the rear motor steamlined cone and drill four cooling holes to help hot air escape. This 3D printed piece is a tight fit in the exhaust hole of the fairing. I get it started and then use a block of wood and hammer to fully seat the pie
