This is an Ocarina that you can play with just one hand! This ocarina uses the English Pendant style fingering with the right-hand holes being the bottom two holes.
This model is currently for right-handed users, however the model can be mirrored for left-handed users.
The two halves shouldn't need any support, though if it is not to your liking, I have included the full model for you to cut.
I recommend not printing the full model unless your printer has god-like bridging since it will mess up the fipple if printed upside down resulting in a non-functional ocarina.
