Nikon F-Mount Pinhole Lens

Hey World!

My first upload. Used the specifications from Nikon, haven't had a chance to print so I don't know how much tweaking still needs to be done.

The design is an f/16 Pinhole Lens; to be used with 400 ISO and 1/500 sec shutter speed. (Let me know if it's close or needs adjustment, I used calculations from mrpinhole.)

Update 2014.03.16
-Printed today on a Replicator 2 with raft and no supports. The inside of the lens is very interesting looking as the filament didn't overlap as I had hoped. Seems to fit my camera great none the less once I cleaned up the mounting sprocket. Will reprint with supports and try cleaning that up; if I am still not having luck, I will have to increase the length of the front so that the angle is increased.
