Made this to organize space in my bathroom. Razor sits in perfectly, easy to put in and out, even if you don't see it (for example if you place this mount behind shower console).
Mounted with 2 sided 3M's scotch-pads.
Modeling was made in Blender, there is a .blend file if you wish to tweak it. But i suppose it will fit many other razors just out of the box.

No supports needed.
