Made this flute for testing reeds on an old pump organ I am restoring. It is great fun. SW Model included - adjust to suit your own reeds.
I printed it in Galaxy Black Prusament PETG with colour change to classic Prusa orange PETG on the sliding part - as per picture. Also - used a brim and textured PEI plate to help hold it down during printing.
gcode for Mk3s PETG attached.
