You can use it as a strange flower vase or as a desk accessory. You can scale the model but be careful that the model is thinner in the mid-height. Depending on the nozzle diameter you may have missing layers.
Designed in 3DSMax. It is a simple extrusion on a simple shape. Added edit poly to delete the upper most polygon to have the gap for shelling. It is twisted. and FFD 4x4x4 then it is mesh smoothed. That's all.
