Air pressure patch for aerodynamic testing

if you're here, you've seen the YouTube videos or maybe you bought the book. Either way you're cheap like me and decided you don't need all that fancy metal when plastic do job fine. This one is full featured (vs the version requiring a metal tube). However, i have no guarantees on accuracy, but i do see pressure differentials increase when testing and i believe since it's consistent, it's fine. 

Be sure to comb through your print settings/preview to ensure the passage is not blocked. 

I used this in conjunction with the following

1. A manometer. Yes it's a little pricey but it works really well
2. Static Pressure Probes (i created a fancy mount for this particular one)
3. Silicone Tube (2mm ID, 5mm OD, 2M, Flexible Silicone Rubber Tubing)

Here's the mount i created to mount the pitot tube in clean air for reference pressures.
