A plesiosaurus banana stand. For all your sauropterygian-based cavendish bearing needs!
Unfortunately, the print bed on my home printer is too small to make this thing large enough to hold an actual banana, so I'll have to try a new print of it on a bigger printer
Make sure you scale it appropriately. .
I modeled it freeform in blender by starting with a 3x3 grid and doing lots of extrusions, subdivisions, and smoothing.
