The 3D model matches the boards and the prints are pretty consistent. The overhang for the board area for FFF may need to be a little more gentle: at normal speeds it can get messy. Looks great using SLA.
For FFF, this was rendered out to use a 0.4mm nozzle, 0 walls, all infill, concentric. This results in a better print as then the printer only leaves the solid area once per layer to jump to the middle 'break off' support for the lower pitot tube. When I say rendered out for a 0.4mm nozzle, I mean that critical wall thicknesses are an exact multiple of the nozzle size. If you want to use a different nozzle, it would be much better to adjust the model and render again to keep this trait.
We have moved to a venturi style orifice and have verified the fit of the PCB and piggy back LCD for on mask feedback.
A ventilator sensor shortage is brewing...
