Wall Mounted Notebook Holder Corner

I use it to put my moleskine notebook neatly below my work desk. I attach it to the side of the cabinet on my left.Print standing up like when it will be used. No support is needed. There are two version, with the hole or not. I'm using no hole myself, using 3M double tape to stick it to the cabinet.For the hole it's using M3 screw, you can screw from the open area.Hope you like it and please tell me if you have any issue.
