Update #5
Hi! I hope you're not getting bored with the multitude of entries. This is an updated design. 1. I'm not too sure when you say to reduce the wall thickness. I am assuming that you are talking about the airway thickness. So, I increase the wall thickness to brace the lower pressure acting upon the walls so it does not collapse. 2. I created a simple cam mechanism to allow delayed exhaled breathing as suggested (short inhale and longer exhale), see attached pics. 3. Added connector to a flexible plate to be attached to a vacuum cleaner outlet. Feedbacks are much appreciated. Thanks!

the valve wheel could have a small tranparent section to show the valve position and have a simple button to push down into the wheel to stop it at the inhale position.

Hi Ahmad, some more improvements, thanks. The walls should all be thinner to reduce the time and cost of 3D printing. Make it only as strong as it needs to be to withstand 50cm H2O pressures and not break if dropped. Have you based the overall size on a common HEPA filter for the bottom? Which one? There are some common robotic vacuum HEPA filters (eg. irobot 800/900: 11cm x 5.4cm x 1.3cm or Miele SF filters: Length: 180mm x 80mm x 28mm.)

both lengths of the valve from inhale to exhale and exhale to the vacuum side has been reduced to increase the sensitivity of adjustment.
