Fostex t50rp planer magnetic driver template

I wanted to make this to use as a model for fitting when I design the cups for my newest headphones. That way I don't have to worry about hurting this thing with saw dust or pulling on the cords. Its not 100% perfect but it will be as close as I can get with wood anyway. This is my first designed 3d thing ever so be nice :).
thanks,
Mark
