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.
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.
