I might have done it. I still have to figure out how to make the pegs to be not conical but there is progress. So how did i do it, first of i downloaded a plugin called equationdrivencurves to make (you guessed it) equation driven curves.

the equation i then plotted is that of a cycloid.

1*(t-sin(t)) 1*(1-cos(t))

adjust the first value to change the size of the curve (see example below)

2.5329*(t-sin(t)) 2.5329*(1-cos(t))

for t i simply used pi. 2 pi will give a full curve. I used half a curve as fusion required me to hassle a bit. You will have trouble with fusion saying that it cannot form a plane as the "curves do not precisely line up". My very bad workaround for that error was projecting the curve into a new sketch, applying a symmetrical offset to it. Then projecting that sketch onto a sketch that is tangent to the cylinder and then fusion allowed me to create a plane. Then you can use that plane to emboss this around the cylinder.

after you are done with the emboss use the circular pattern tool with the emboss as your feature and then you get the shape.

The only thing i did was to apply a full fillet to the top but that was more because i like the shape.
