Summary

I printed off a couple of the Wall Mount for Vtech Cordless Phone shelves, and then a new phone base had a permanently connected cord, and the power supply would not fit through the square opening.

So I've made this slight change to the model to allow a cord to be slipped in before the wall mount shelf is mounted on the wall. The slit is about 3mm so it should allow most cords to fit through it, without altering the ability of the phone mount to hold the phone base securely in place.
