This model requires a printer with good cooling to make sharp edges inside of “whistle mechanim". One of my printers - kingroon KP3S can't make it, but QIDI Q1 made it perfect. So this model can be a good test for printers.
It sounds better if printed with PLA and layer 0.12 mm.
Свистни в хуй!

I added whistle.
