Failure, SPI version, and pretty things.

A project log for VISP - Ventilator Inline Sensor Package

The snap-off support for the lower pitot tube worked, but was bonded a bit too well and took the edge of the tube with it.  Moved that down a bit, made the tube one wall thickness thicker.

<EDIT> That worked.  Snapped off perfectly now.  We are dropping the latest one on a table saw to check the internal port geometry today.

</EDIT>

The board got some minor revisions as well, with the bypass capacitors for the sensors move next to them.  They were probably close enough before but that gave us a little more wiggle room for routing... 

The SPI version!

So we modified the 3D model to match, again, and that is printing now.

Some other eye candy.
