I was annoyed that almost all cheaper razors in my region came without a holder for the handle and blades, wich is useful when travelling so that you dont cut yourselves when grabbing into your traveling bag. The clips secure the handle, so it cannot fall out when upside down.

At the back of the holder you can store the bladeholder in both directions. This is useful when you want to travel with more spare blades and don't want to have someting extra in your bag.

I reccomend printing the holder with tree supports because it can be a little difficult to remove the standard support structure.
