A weird idea I got after printing the Prusa Mini demo bolt and nut: a spice shaker/bottle shaped like a bolt. The purpose of the nut is to close the hexagonal sprinkle hole while you fill it up with your favorite spice, but it's also nice to fiddle with if you're bored and all you have is your weird printed spice shaker.
I've printed these with my Prusa Mini using Prusament PLA and PETG, 0.2mm layer height. Nothing special in settings, except maybe avoid crossing perimeters to avoid stringing inside the bottle if you intend to fill it with something edible. These print without supports, so no post processing needed, the threads will get smoother the more you play with it.
Maybe don't print a full spice rack of bottles with the same filament, color code your bolts with different caps or nuts?
I printed some simple washers to label the bottles, but these make the bottles awkward to hold. Need to find a better way to label these.
Also I might add another hole-configuration in addition to the single hole shaker body, many small holes is probably better for finely ground stuff and large ones for stuff like chili flakes.
