Having a range of spice jars, most spice racks don't fit, so I made one of my own. One module fits three larger pots. Thicker double-sided tape fits in the slots at the back (I used Tesa-tape).

The stl contains one module, one end-stop and four plugs, which can be used to align neighbouring modules. The module prints sideways-up.

Edit: for convenience, files of the individual parts have been added
