Help with wrapping an object around another object

[Yepher]

Here is an attempt from the best I can tell from the photo you shared. Maybe you can use an approach like this.

1. Make a cylinder
2. Create a block and project the circle onto it
3. Make holes in the shape of the part that protrudes
4. Rotate the block to get the angled taper
5. Subtract the block and cylinder

Or use the process Tigermike shared but instead of rotating flat to the cylinder rotate it at an angle.
