This holder, together with one of the very cheap suction cups with screw/nut interface, makes a very nice every days storing fixture for your razor.
These are the suction cups that I used, but there are various types around with very similar size.

In a pack, they cost little more than 1€ per piece.
The razor is held by the blade, with the blades facing into the part to avoid the risk to cut yourself accidentally. But great care was taken to allow the blade to dry off within the holder to limit the number of bacteria that may grow on the blade over the days.
The part is specifically made to fit razor blade sets from discounter Aldi, with a width of 43-44mm. But all similarily sized razors should fit as well.
Printed upright in PLA on a Ender3Pro and in PETG on a Prusa i3 Mk3S. It is very easy to print, so it should work basically on all printers with all materials. The round opening for the suction cup screw is intentionally slightly oversized, so it can be printed without supports. The slight imperfection on the top inner side of the opening is not visible after assembly and does not matter.
