Not sure if 0.035" would be thick enough though.

It would probably be fine. If I ever get the urge, maybe I'll start there.
For now, it appears that one or two people might want exact Herse reproductions, which will be a bit harder to do because of this tubing situation. It may require messing around with Aliexpress or some such. Stainless would be a bonus, since it's pretty hard to get things chromed these days.
