Here is one that look similar to your hand sketch.

I used surfaces to match your sketch and also patterned it around.

I slice the curved edge from the right plane, mirror and pattern, then slice the outside round edge from the front plane, and pattern.

Here is the 16 vs 10 version you asked about. I forgot you don't have SW2017
