Nikon F mount to c-mount adapter
thingiverse
Adapter to connect Nikon F mount lens to Raspberry PI HQ Camera (c-mount). In design there is a block which turns the lever which opens aperture completely when you twist lens for connecting. Be careful and do not overtighten the adapter to lens. You need to carefully adjust the backfocus ring. I managed to get my 18-70mm lens to focus from 30cm to infinity using camera focus ring when properly backfocused. Use filament that does not pass any light through, preferably black. My red filament prototype caused reddish tint to all photos... Also prototype required 5mm extension tube to reach correct backfocus. I hopefully corrected this in final. (Didnt try yet...) I used 20% infill and support only touching build plate. You need a 1/4" nut if you want to connect adapter to a tripod.
