Cool.
Good idea mine falls off all the time. It is laying on my dresser right now. Looks like a good project. ThanksFor almost three months I was laying in bed due to a fracture in my right ankle.
I spent most of the time watching Netflix and Youtube by means of Roku. This streaming device had a double face tape to attach it to the TV but, the tape did never work. To keep the Roku in the horizontal position I placed it on a small carton box.
As soon as the doctor removed the plaster I went to the garage with my crutches and made a little cradle for the Roku. The cradle has a 2 inches collar that fits snuggly on the TV base. It has also an open bottom to allow air circulation.
Problem solved.
