We trimmed back a couple of african violets and wanted to try growing a few of the clipped leaves in some 25mm diameter test tube thingies we had laying around.  I threw this together to give them a way to stay up without leaning against other pots.  Maybe not the most common need, but here you have it.

I added the names in prusaslicer by right clicking the model and adding text with “use surface” checked :)
