Print In Place Adjustable EDF (Electric Ducted Fan)

Something I made at midnight - a basic (possibly print-in-place) EDF, for RC aircraft. It uses a 3mm grubscrew to tighten down the wing tips, so you can adjust each blade by hand after printing to make sure it's juuuuuust close enough to the duct, to avoid performance issues.

Enjoy, and let me know how it prints (and if it works)!
