Hi @Anonymous,
I whipped this together quickly - I can make a screencast later.
I swept the outer edge as a semi-circle then made a midpoint plane to create the horizontal bars. I extruded a circle (2mm) using the 'To' extents, I just mirrored that bar and then used the rectangle pattern set to adjust to repeat the bars down.
The vertical bars use a similar process except the endpoint is created by projecting the outer round edge of the semi-circle and extruding as a surface. Then created a plane along the straight edge and sketched a circle, extruded using the the 'To Next' extents selecting the extruded surface. Finally, you can rectangle pattern using the adjust compute
