** new version is out!** https://www.printables.com/model/798714-automatic-chained-organizer
It's my first design so it have somes flaws. It can only turn well in one direction and some fits may be too tights for some printers. However, it's a fonctionnal print and only uses 4 skateboards bearings (8x22x7mm), no glue. It's stiff enough to be transported and i've made differents sizes to fit most shelfs or refrigerators. I also made a wheel version that's meant to use without any bearing. The fit is too tight for it to turn so it will create more friction for sure. Keep in mind that i only printed the 18 sauce version so the others are not tested, but the lenghts are carefully mesured. The wheel_no_bearing isn't tested as well, and is not recommended.

The 18 sauces version is 56 cm long, and the others are shortened by 2.9 cm for each sauce removed.
Feel free to give any suggestions!
I printed mine using an elegoo Neptune 4, 220x220mm bed.
I used PLA+, it's probably not necessary but I think it helps the caddy to be strong and flexible.
My settings were 0,28mm layer height, 5 floor, 5 top, 4 walls. With a 0.4 mm nozzle.
I used gyroid infill.
I only used support for the caddys and the wheels.
I would also recommend sticking the print to the shelf with double sided tape, or else it will move when tuning the conveyor.
I added the step files for the 18 sauce version.
I modified the Wheel no bearing for looser fit and shorter shafts, they were too long.
I uploaded a new version of the Wheel_bearing with new extrusions to keep it centered between the carrousel top and bottom.
