Sketching / extruding along a curved surface

Hi! Long time (off-and-on) relatively low-skill user, first time forum participant.
I have a dust collection adapter with some compound curves -- a square design at top narrowing to a hollow cylinder at bottom -- that I'm 3D printing in four parts due to limited printer bed size. I've actually printed a V1 of this design successfully, but I'm unhappy with how the single "puzzle piece" style connector at the top of each part allows the bottom to float freely; it doesn't perform well under the stress of the dust collector suction.
I'm trying to add another "puzzle piece" style connector on the vertical column near the bottom -- you can see my first attempt here. However I can't figure out how to make a sketch or an extrusion that follows the curve of the cylinder.
Hopefully you can see the issue in these images, or if you have time, you can check out the part here. When I draw the puzzle piece on the plane formed by the edge of one part, it extends straight out, when what I really want is for it to follow the curvature of that circle. I've tried messing with Ruled Surfaces (you can see one in gray in the final image), but I can't figure out how to create a shape along such a surface. Basically if there is a way to extrude in direction = "blind but along the specified surface" then that would instantly solve my problem.
Thanks in advance!

This might not be the cleanest way of doing it, but if you are this far along, you could use a couple of replace face commands to get the curves you seek. Another option is to create a surface to extrude up to. And there are probably many more ways to get there.
