Scale model US 1/2 barrel beer keg, for your diorama needs. This was designed following dimensional specifications of the 15.5 gallon US standard 1/2 barrel keg (23 3/8 inches tall, 16 1/8 to 17 5/32 at swells).

To convert to 1:10 scale, scale all dimensions in your slicer to 254% (so height = 59.18mm).
To convert to 1:12 scale, scale all dimensions up to 212% (so height= 49.32mm)
To convert to 1:18 scale, scale all dimensions up to 141% (so height= 32.88mm)

Sidewalls of the base and riser were thickened a bit to be a good print when scaled to 1:10 and smaller scales. Overall design intended for 1:10 scale at .20mm resolution, with a .40mm nozzle. At smaller scales, suggest increasing your print resolution to .15 or .10 layer height.
