Bate Pole - Floating cup.

thingiverse

This is a custom cup designed to attach to a bait pole. The idea behind it is that you drill out the end of the cup to match the diameter of your pole, then screw in a bolt so you can easily remove it for transportation. To create this design in Cura, start by making the handle part (the section that attaches to the pole) with 100% infill. This will give it the strength needed to hold up to drilling and attachment to the pole. You can use any other infill setting for the rest of the cup since its primary purpose is buoyancy. This initial version has some flaws, but it should still work as intended. The .stl file is editable, so you're free to make any necessary modifications or wait for a revised version (version 2) if one becomes available. The attachment measures 50mm in length, 40mm in width, and 40mm in height.
