Swimbait Fishing Lure "KATS O FIS". Made of 5 segment pieces.
The lure is about 16 cm long. Length and everything else can be modified through the .scad file.
Main body parts are printed with PETG in one go. The fin and tail are recommended to be printed with flexible material like Fillamentum Flexfill 98A or alike. However, the "Kats o fis" seems to swim well without the fin and tail, slightly different way though - please check out the videos. The fin seems not to have very much effect on swim style. Fishes will decide which way is preferred eventually.

The printing has to be paused & resumed few times for weight balls and hook rings installation. Please consult the slicer software preview mode to define the pause layers.
I didn't have suitable eye bolts at hand for the hook to body, so I had to use the 9mm rings instead.
The hinges are made of 0.9 mm diameter stainless steel wire. The wire is pushed down from top side of the hinge. One can lock them in place by touching the top of the hole with soldering iron for example if the wire is cut slightly short from the top.
I've used 4.5 mm diameter air gun steel balls as weights. They can be made of other material too, but the chambers inside the body parts (2,3,4) are for 2 x 4.5mm balls currently. One can modify the .scad file to for different weights and weight chambers of course.
Color doesn't matter if the lure is painted
Infill rate maybe set 20%-50% depending how much it needs to float. Depends on selected printing filament too.
For durability, especially the nose and tail parts (1. and 5.), it is highly recommended to anneal the parts in oven for 1 - 1.5 hours in glass transition temperature of the used filament (PETG about 85 Celcius in this particular case).
The tail material is actually printed as sheet of material that needs to be cut to right shape. The fin is ready to go and can be pushed to the hole in part 4.
Finally, for attracting the fish it may do good to have some paintings on it. Not sure on this part though.
The lure was designed with OpenSCAD. Please check out the attached "fish1-5.scad" file, customize as needed. There are not much comments in the file, but those familiar with OpenSCAD may find it useful still.
