Toothpaste holder designed especially for Elmex toothpaste, but works for every lid that has a diameter smaller than 34mm.
It should be possible to scale it directly in the slicer for other lid diameters.
I used double-sided tape to attach the holder on the tile.
I used Prusament PET-G but pretty much every other material should work as well.
0,2mm layer height and 15% infill worked fine for me.
I also used automatic generated supports.
