Patterning on a diagonal cut from a cylinder

Working on patterning a nub around the inside of a diagonal cutout from a cylinder.
I want all the nubs to be perpendicular to the axis of the cylinder, and equally spaced around the ellipse that is inscribed on the inside.

I've attached the part. Haven't been able to get what I want yet without having to manually place all the instances.
