Have you ever bought a large 3 ring binder and noticed it had these plastic flippy pieces included? Those have a useful purpose and a name!
Without sheet lifters, when a binder is closed, if the sheets jam in the hinge it places unusual force on the hinge, as well as possibly straining the paper against the weak edges of the holes.
Sheet lifters will save the lead sheets from excessive wear. They act as levers, and help prevent the holes from tearing by guiding the pages gently toward the center of the rings when closing the binder.
I have included two files - a full size and a smaller 2/3 size for smaller print beds.
The full size lifter prints fine when placed on a diagonal on my Prusa i3 Mk3.
