Gậy escrima Nightwing (Gotham Knights)

Newest addition to the bat family arsenal, Nightwing's escrima sticks, grom the game gotham knights
this was based on a mix of concept art and some of the ripped game models
concept art source here

modeled this in as many pieces as i could, to make printing and sanding easier
the final pice measures at around 600mm

there's a space across all of the pieces for a 4mm rod to go trough, to keep the pieces aligned when assembling it and to give the prop a bit more structure (these are for wiggling them around after all!)
Rod measurements: 4mm diameter, 480mm lenght

There's also a hollow space on “main body top” for lights, and “tip” is meant to be removable from it (for easy access to replace batteries or change the lights, etc…)
how this (ideally, its not been tested yet*) will work is, put a sheet of plastic (PETG, Acetate or those translucent plastic cover from a notebook, whatever works) inside the hollowed out cylinder, feed in the lights and batteries inside, and close the top with the “tip” piece
(its friction fit right now, but i may add spaces for small magnets if it needs to be extra secured)
