I recently bought the above mentioned scope. Not bad for the price but it had no hood. This made it difficult to use in sunlight. So I designed this hood. I printed this in eSun PetG for flexibility.
I also used the Slic3r Prusa edition variable layer height to have a very fine layer height in the threads area. The rest printed at my usual .20 layer height.
Used variable layer height in the threaded area
