Now that I have that off of my chest :), here is my "saw it on Pinterest and did it" project for the day. The hair dryer storage using a magazine file.
I placed two screws on either side of the top just inside for both.
I also found that you need to secure the bottom as well to make sure it doesn't move around too much. I used the hole on the spine to place one more screw on the bottom of each. This was hard to photograph, but here's the bottom screw on the solid one.
And here it is on the mesh one. This access hole on this one isn't very big, but it was still easy to secure the screw.
Again, don't use screws that are too long and ruin the front of your cabinet. Also, if your cabinet is "raised panel" make sure you are placing the screws in the right places (where you have the thickest part of the cabinet).
This is a must do if you own a hairdryer so get on it : )
