Leitz darkfield condenser plug, fully customizable

Here is the design for the "stray light plug" for the Leitz 0.80 darkfield condenser.

The design has been reverse-engineered from old Leitz catalog illustration and user measurements.
The default values in the Openscad are those considered most realistic;
Also two .stl of the finished product with those values, one full (3D printing) and one as thin shell (the original one).


Recommended print material is matte black ASA, or CNC from metal + blackening.
