The file 'Rotation Hinge For All Moving Tailplane (RC Plane) 3D Printer Model' is (stl) file type, size is 3.1KB.
This is a little "bearing" that has a lot of friction
But, it does its job as a hinge for an rc tailplane.
So, slot the nail shaped piece through the cylinder, and attach the smaller end to what you want to rotate
voila
