This is just a nice way to carry your bottles of juice while keeping them organized. Also looks nice on a tabletop. All 3 models have the same swoop in the back. I just haven't printed the new version of the 4 and 5 bangers.
I printed mine in Bambu PETG at 0.2 layers, 3 walls, 8% gyroid infill, 6 top and bottom layers.
The 6 bottle rack only fits the bed if you print it diagonally.
All my bottles are 100ml so I can't verify the 120ml bottles fit.
