The design
A hollow Ionic column with 24 long grooves and a bulb inside. It's a stack of drums with the top cut on a slant.
The drums push together with small ribs, a tab and two hidden pegs. No rod or bolt through the middle.
The hollow base prints in four quarters. Fill it with sand. Vents around the socket and the open top make the column a chimney.
The crown swaps the slanted top for a capital of acanthus leaves, the carved head of a column, in four quarters. It's a new take on the capitals at the Getty Villa.
Floor, table and desk sizes. The desk column is one print with a hollow chamber for a regular bulb or an all-in-one lamp.
