it's really good design of it I did scale it down cuz I wanted it to be h o n 3 but it's really good model I did have a couple issues putting it together like the axles wouldn't fit right but yeah it

Works great

Great job on the track. We are making a loop now. then I will print some more. You working on switches?

Fun print

Simple and fast.to make. And uses very little fillamemt. Works, as good, as a larger whistle but is compact. I also love that it has a ho e.so I can thread something through it, to hold it to my pack, or make into a necklace.
