Ventilator Prototypes-I NEED YOUR HELP NOW

thingiverse

I'm working on these 3 designs with NEMA 17 stepper motors to create a last resort option for patients that would otherwise die without access to ventillators. I would appreciate any help from all the experts in design. I am an anesthesiologist with no expertise in coding or electronics; I am using a CR10 MAX printer on PLA. I made a prototype from wood (temporarily broke my printer) and you can see it in action here: https://www.youtube.com/watch?v=SI2yv-K0nfQ Please know that we are only weeks away from having to decide which patient whom would otherwise survive to let die. * There is significant use of other's designs incorporated into these models. I want to apologize for not giving credit to the original creators at this time. I will credit them appropriately as soon as I can. * I need your help with making sure these designs can survive continuous use for at least 2 weeks. I have never designed anything that needed real understanding of force vectors or any structural components. I am fairly new to 3D printing. Additionally, if anyone can see flaws in the design or anything that should be improved, please let me know. I would really appreciate any help I can get. I just uploaded an updated design for a NEMA 23 motor. I need the device to handle more pressure. Can anyone tell me a way to slice this with cura or modify it in any way in tinkercad to increase the strength of it. I need the gears to last at least 14 days of continuous use.
