Body of a spin tail lure.
The lure is printed in two halves and then glued together. I made three small holes with 2.5mm depth on the inner side of each piece. Together with the holes, a PLA filament cut in 5mm length can be used as a tenon when you glue the lure. Two bigger holes are for placing sinkers. A ball-bearing swivel is to be attached to the tail part so that a metal blade rotates correctly.
The finished products shown in the uploaded photo are printed with fluorescent filament. I hope this works well in night use.

*Change of infill settings (30 November 2021)
I recommend that you print at 100% infill.
I have found that the initial setting (50%) causes extra buoyancy and the lure does not sink properly.
