Hi,
as promised here is a report on the Bussard collector rotors.
They are built up from 3 main layers of 0.5mm plastic sheet,
with another 0.5mm layer between to give them more depth.
The fine details were improvised with small basic triangles
and rectangulas.
The whole assembly won't be seen too detailed through the
dome, so I didn't care too much about clean cuts.
Perhaps I'll glue the rotor to a disk of frosted clear plastic
to give it more strength and to diffuse the light from behind.
Here is the template sheet for the rotor parts, perhaps
someone finds them useful.

The paper can be glued to styrene using a waterbased glue
stick, and after cutting, it can just be washed away with
water.
Next step is filing the intake to a more correct shape and
installing the servo motors.
