Every cell takes a pot or a dropper. Pots sit in a shallow pocket on top of the deck, and droppers go through a bore in the deck onto a ledge. Each row stands higher than the one in front, so you can read every label. Underneath it's all thin-walled hex cells, which keeps the print time down.
The STLs are a 5×4 module of 20 cells and the two ends that go with it. A left end adds four cells and a right end adds two, and each steps its side back to match the rows, so the three together hold 26 bottles. Every module shares the same hex pattern, so a second 5×4 fits right up against the first.
The default pocket is 33.3mm, which holds Citadel pots snugly with a little play. If your pots or bottles are a different brand, print a single cell from the .scad first and adjust.
For other sizes, open paint-rack.scad in OpenSCAD and use the Customizer panel (Window › Customizer). It needs a recent development snapshot of OpenSCAD (2024 or later), because the 2021.01 release is too old.
What you can change in the .scad:
Pieces: the module, a left end, a right end, or all of them on one plate
Size: columns, rows and cell size
Steps: front deck height and the rise for each row
Pot pockets: depth and diameter, or a depth of 0 for flat decks that print faster
Dropper seats: bore diameter and depth, and a push-out hole for a stuck bottle
Wall thickness
This is part of HobbyKit, a free generator I made. hobbykit.app does all of this in a browser, and can also chain modules into a longer run, turn corners and add brush holders.

Upright, as the STLs load
Supports off. The decks bridge between the walls, and auto supports would fill every cell.
0.2mm layers. The 5×4 module takes about 5 hours on a Bambu Lab X2D at 0.20mm Standard.
