To sharpen the blade and polish the channel both can be slided out and are easily acessible with files or sanding paper. The sliding also should permit adjustment for maximum loudness. (It needs to be tweaked since at the moment it is loudest on the maximally open position)
This whistle is designed in such a way that no flat top printing surfaces are visible to the internal chamber meaning that even if your flow settings are a bit too low the chamber will still be airtight. Its made out of two half-shells to avoid any internal overhangs.
Print the two mirror symetric halves the channel and the blade.
Use full support for the channel and outer support for the blade !!
Use a short piece of 3mm diameter filament to lock the two halves together.
Additionally use a bit glue to seal the seam.
Take care not to get the glue on the outside surface (ugly)
Stick channel and blade into the main shell. File a bit.
