Great idea! I also like the idea of taking an existing product and "hacking" it. Too bad first thing you need to do is worry about getting sued...
I can draw anything in CAD but I have never seen a ventilator or its components before. I have the capacity and capability but will need input from someone who knows what it is that we need to make.
Separately: The UK government asked for the manufacturing sector to use their capacity to help produce ventilators. The last time they asked for similar favours, I think it was for Spitfires and Merlins. F1 teams are looking into it. I volunteered my time and hope for once in my life I can do something meaningful for humanity. To be continued.
Italian companies are doing it:
