Eylet attachment for Caperlan LAKESIDE-1 700

This is an eyelet attachment for the tip of the Caperlan LAKESIDE-1 700 fishing pole, for using the pole as a mast/support for amateur radio and other, mainly wire antennas.
The attachment is designed to be inserted into the second highest segment of the pole (see photos); the topmost, thinnest segment is not used because it is too weak and flexible. In this configuration, the pole reaches a height of about 6m to 6.2m.

The attachment has an eyelet large enough to pass a wire or rope through it, even with a small carabiner or insulator attached, without the need to remove it. Alternatively, the carabiner can of course be clipped onto the eyelet.
The dimensions of the attachment allow it to remain permanently inserted into the pole segment, fitting under the rubber cap.

It is recommended to print it from at least PETG or a better material.
The part is oriented directly for printing; supports must be used! Printing it upright would make it too fragile.
For a 0.4mm nozzle, I recommend a layer height of 0.2mm and 7–8 perimeters (so that the part is printed solid, without voids).
The attachment should fit snugly into the segment; if the attachment is too loose or does not fit, print it slightly scaled up or down.

Recommended additional parts:
The Lakeside-1 has a rather fragile bottom cap; here is a very good and sturdy replacement that also fits the Lakeside-1 700: https://www.printables.com/model/48453-caperlan-lakeside-1-fishing-pole-cap
For use as a guy ring, I’ve had good results with this model, specifically the 1-inch diameter version: https://www.printables.com/model/493464-mast-guy-rings
