Im having trouble wrapping my head around this structure idea. Id like to draw an object at the edge of this tube to act as a retention mechanism when slid into a larger diameter hole. But I dont know if I should be extruding an object on one face and then rotating around an axis. Or if I should be adding custom planes and drawing on those. Or if I should just draw a larger diameter tube around mine, extrude it and then chamfer that edge aggressively to make a coned lip.  
Any ideas?

larger tube example seems close enough. maybe its fine to just use this? is there a right way to do this?
