First picture can be build with 2 shaft 1 symmetry and one pad. (no fillet needed)

Second picture can be build with 2 shaft and one fillet. If you want to add threads as seen as picture you need extra 1 rib to create teeths.

In first picture red show shaft axis. Green and light blue are shaft sections. Make symmetry green shaft. And orange is pad. You will need pocket or hole for this also.

In second picture. Red and pink show axis which are perpendicular tu each other. Light green and yellow shows shaft sections. And green arrow is fillet.
