Rokinon 14mm filter holder for APSC camera (Z filter)

I built this filter holder to use with my Rokinon 14mm ultra wide angle lens on my APSC cameras.
Is buit in 5 parts. a semi cilinder that sorround the actual hood of the lens, to prevent reflection from behind in the filter, two actual filter guide (you must to glue this to the semi cilinder), and two litle pieces to hold the screw (headles). There is a space for a 8mm nut, you must glue this too.
This works fine with an APSC camera. In full frame cause an ugly vigneting.
Warning. I made this again after breaking my old pringting, but in Blue PLA. i dont recomend using light o other color than black, because will cause reflections in your filter and a nasty artifact. i recoment sand the inner part, until no reflections can be seen.
