Today's updated design, laser-cut and assembled in its final form. It is sat inside the outer cardboard box. You can't see the saddlebag that's hidden at the bottom, nor the battery that's in the centre of the assembly. Some of the strip of RGB LEDs can be seen, which are looped around the battery box and holding-tabs; there are some velcro ties just about visible in that loop too.
The top of the insert has a green (because the prototype board was more readily-to-hand than the production red versions) My Bike's Got LED circuit board on top of it, held in with cardboard tabs that fit through the PCBs mounting slots.
Rounding it off is the @MCQN_Ltd@social.mcqn.com logo etched into the cardboard, and the instruction zine folded up and tucked above the battery
