I'm just showing off one of the biggest pains in my ass fabrication projects I've completed. It's not pretty, but it also doesn't leak so that's winning. 3 separate 30ft coils of 5/16" OD stainless running in parallel. It's kind of similar to Jaded chillers but the stainless ones have been out of stock for a few years and I needed one. No, I'm not interested in making you one.
