Results from the venturi comparison with the original design. Data is at this link: https://docs.google.com/spreadsheets/d/1CylfLKrE64rkY6gbZZj0AzY_0tv3djxfM-mScOxUXCw/edit?usp=sharing  - The modified design produces less restriction of...
Here is a plot summarizing what performance goals we want for the venturi:

We will probably want to use DISS-compliant medical oxygen fitting such as this one: https://mfimedical.com/products/allied-healthcare-diss-male-to-1-8-npt-male-fitting-with-check
We can use something like this to mount the DISS fitting to the acrylic: https://www.mcmaster.com/7880T341-52065K401/
The 1/8" NPT DISS fitting will not fit the specified (1/4 NPT) panel mounting solution. Here is an alternative: - 1/8" NPT DISS fitting: https://mfimedical.com/products/allied-healthcare-diss-male-to-1-8-npt-male-fitting-with-check - 1/8" NPT Panel mount:...
mounting bracket for the regulator can be found in the datasheet: https://www.smcpneumatics.com/americansmc/SRH/SRH_Series_Regulators.pdf
I recommend picking a unit that has the specific UPS capability and at least 200W continuous of power delivery capability to provide margin, more if you go to the higher...
