Mast Top Pulley

thingiverse

With a rounded inner, this mast topper enables rope to slide effortlessly, lifting an antenna or flag with ease. This concept is off to a great start, but I believe there's potential for refinement in how it attaches to the mast top and enhancing the smoothness of the pulley action. I'm inclined to re-design this model, yet I'll leave this initial version intact as a starting point for further exploration.
