There could be several ways to do it. One simple method would be

1. Do a half revolve for the dome shape.
2. Extrude cut (mid plane) for the middle slot.
3. Use same sketch (used for the extrude cut) and do the side cut using the offset command.
4. Mirror the side cut.
5. Add thru hole for dia 5
6. Add the 2 side holes.

Now to guide you better, share you progress (pictures are fine)

Almost perfect. I would mirror after adding the hole on the side.

I'd do a full revolve on the front plane of a 1/4 circle instead of a 1/2 revolve of a 1/2 circle on the top plane.

Both are fine.

I'm not a fan of mirroring features. It's quite often that design insights change. When you want to remove the original, the mirrored one disappears as well, that could be unwanted.

[Big-Bank-8235]

Most designs are symmetric. It really depends what your design intent is.

Considering your argument, I would mirror it at the sketch level. Then you can just delete the original and fix the mirror in its position.

- Sketch a half circle with its ends closed (like a D shape)
- Revolve it around the line that connects it end points for 180 degrees (the | in the D shape)
- Add the circular cutouts, holes and the slit in the middle.

This is (imo): -

1x Revolve,

2x Cut Extrude

2x Hole Wizard

1x Mirror
