Easy two piece wall mount designed for my Doug Tipple Irish flute. Also works with my Nuvo Flute, but the fit is a bit looser. The bottom piece prints in two parts, the peg and the mount.

Do not glue the peg in after screwing the wall mount in or you will block the screw. It should fit well enough with friction. You will likely need to clean the elephant foot off of the bottom of the peg to get it to fit properly.

The top piece is just small enough that it snaps around the body of the flute and requires a little flex in the material to remove. For concert flutes you will likely have to adjust the width of the model in the slicer so that the gap is slightly smaller than the body of the flute. The model as-is has the gap at ~25mm I think.
