Hi,

My process has been :
- a simple curve of the form


- I trim it with a line to have 2 curves which could become 2 rails for an sweep of an elipse




- I sweep with the 2 rails




- I use a blendCap for the round end


- I do an offset shell to have a thickness



- The bead is done with a cutted version of the inner part and a offset shell with more thickness


- Ended with some filleting.





The bail is one of my standard obj library part I've done years ago (I don't remember how I made it... Sorry with years my memory fails
