I couldn't find a salt shaker that suited me, so I designed this one.

I provided two sizes; the larger one is about 4 inches or 10 cm tall the other is scaled at 66% to about 2.75 inch or 7 cm. To customize, just scale the larger version to whatever size you prefer in your slicer. If you go much smaller than 66% though, you may have trouble with the thread clearance. That said, the tolerance is fairly large and should work with most printers. The top piece should be printed with supports. The bottom doesn't need them.

I printed with 0.05 layers and concentric top layer. I think it came out very nice.

Don't forget to use food-safe filament for this.
