Reference image: 12 mm on the caliper to calibrate, tried to take an undistorted picture

We inserted a canvas and right clicked the image on the dropdown. The Calibrate tool allowed us to set the distance between the caliper hands to 12 mm and scale the entire image in suit. This allowed us to use the line tool to trace the outline of the wishbone close to perfectly.

We extruded the form resulting from tracing the wishbone. In that process, we also traced the inside triangle because it is important for stress absorption. Thus, we have the basic frame of the wishbone and further details could be added through extrusion and fillets

Once we had a rough body of the arm, I measured the holes and started to add them for the screws. I first rounded up the edges.

I added holes onto the left of the arm and used "Fillet" feature to round up the outer edges.

Then I added the second circle on the right

I tried to make it the shape round shape as the actual arm

I used "Extrude" feature to fill out the sketch so that the outer edge formed a circular shape.

Then I extruded out the part and created the hole on the right side of the arm.

We attached it to the right side and it was able to fit; this is the view from above

Wheel end: there was no metal attachment so it did not fit perfectly

First iteration 3D print (top and bottom)

This is what it looked like closer up

Inner end: the hole was too narrow and led to a tight fit for the rod

I enlarged the hole on the inner end for the rod. I widened it so that the diameter was 2.85 mm. We did not change the hole on the wheel end because there was little we could do without the specific metal attachment that would be worth the effort. Since the screw went all the way to the other end, we decided it would be secure enough.
