Saw a few versions of this idea and decided I would make a simpler version. I saw some designs that included an elaborate coiling under shelf but that seemed unnecessary. I first thought about cutting cord and adding new plug to make the cord about three inches long but decided for usefulness I would just use a rubber band for the cable. My first thought was to have indentation for the Sonic charger base but I am also including a simple design with flat surface.

The first file is 6mm thick(with lip around plugs) and the second is 5mm (without lip). I did this to make it easier for the short screws to connect better.

I think 15% fill is sufficient but since it is a small print I print at 100% to make it stronger.

A friend asked for a mod and so I added 2 more files to my original design for adding a holder for a tube of toothpaste, one on the left and the other on the right. I also added additional files for those who may have the 2-hole version of outlets instead of the single rectangle hole.

Another request for cord storage, I was going to do a remix of this design but just decided to add the new files here for a version with the cord storage and I couldn't find a way to make it an easy print and I didn't want to have complex support, so I compromised by adding 6 new files.

For the 2-square hole outlet I am including 2 files; to include a single piece fixture with a storage compartment, one for a flat surface and one for a top surface with indention for Sonic base.

From the original 1-square hole outlet design but adding storage, I am adding 4 files. Two as the one-piece fixture with cord storage, one flat and one Sonic. I am also including two files as separate storage pieces, one flat and one Sonic, to add to the original no-storage fixtures in case you print with no storage but want to add it later. You will likely have to use glue to secure the storage to the original plate.

For the versions without storage I suggest you print upside down. With the one-piece version with storage I would suggest printing on its back and use PLA with PETG filament as top layers of regular support interface. This should make the support peel off with minimum scaring. I have not printed this one-piece version, but hopefully the design and support is successful for you.

This should cover all options. I am sorry if all the files make this confusing.

I look forward to comments and pictures of makes.
