This was created for a Yak Attack Park n Pole anchor pole (.845" diameter). Instead of attaching the anchor line to the top of the pole which can put more sideways pressure on the pole and cause it to pull over, I use a loop that allows the floating anchor line to rise up and down with the surface of the water. This stopper will prevent the loop from sliding off the bottom should the anchor pole become unstuck. The lower portion is slightly flared out and is used to jam against a rubber band or o-ring that will prevent it from sliding down but still be re-positional for different water depths.

To install, slide it onto the pole (flat side up). Slide a small rubber band onto the pole afterward and set it to the depth you want the stopper to stop at. I typically fish in 2 - 3' of water so I put it at 2.5'. Then slide the stopper over the rubber band. This will jam it in place and prevent it from going any lower.

I printed in PETG at .2mm layer height. It's been used frequently over 2 years with no issues.
