Case Moth

Most probably a case of a case moth. I found this structure at the underside of our wooden fence. It is 10mm in size and sticks out and down in a 35 degree angle from roughly west to east. I placed it in the Cania genus, but firstly this genus is doubtful (I think that name was taken by a different taxon). Secondly, at the moment, any ID is tentative. It mainly serves to remind myself of this fancy group.
