I recently needed to make the bathroom a little neater.  Some things in the shower were just in the way, namely Sonya's razor and her Olay ProX face scrubber.  3D printer to the rescue

The main issue with the razor really wasn't that it was in the way as much as that while it was lying flat, it stayed wet and the blades eventually got rust on them.  A hanger could definitely resolve that problem.  I designed a two part bracket in 
and mounted it to the wall using a waterproof 3M Command strip.
The success of this bracket compelled me to modify it slightly and create another mount for her Olay ProX exfoliatior.
The angle of the razor bracket is 15 degrees in the Z axis, but I probably could have gotten away with 12.  The ProX exfoliator has a 10 degree angle in the X axis and a 5 degree angle in the Z axis.  Printing in two pieces provided the necessary structural integrity, and allowed me to print without supports.
By the way,if you haven't tried razors from Harry's, you don't know what you're missing.  Good shave, great price, delivered right to your door.
