3D model description

This is a fairly accurate rendition of a Mitchell NC camera lens c1950.
The aperture ring & hood section has been used to "repair" an actual NC lens that was missing the part (1st photo).
The other sections have been used to exhibit a real Mitchell NC camera with blanking plates and dummy lenses (last photo).

Any magnifying lens between 20-23mm diameter can be used to finish off the "lens".
No actual helicoid is included, the lens 'focus movement' is a push fit.

Also included;
Lens turret blanking plates
M42 lens to Mitchell NC adapter (to mount M42 lenses on an NC camera). The adapter fills the 2.46mm difference in flange depth, and should enable infinity focus with M42 lenses.
Mitchell NC lens back cap (v1 for flexible plastic, v2 hard plastic)

3D printing settings

FDM: most parts should be printed with the front of the lens on top (ie the last part to be printed). 0.2 layer/4mm nozzel, with support.
lens caps: printed top face first, brim & no support.
