Núm chỉnh âm lượng Logitech (Z533)

It was always a struggle to see the volume level on the original remote control knob. I decided to create this knob that makes it easier to see the volume level and also easier to grip. To create the visibility I made the indicator line white. 

I did not design it to be a press-fit, so that I can remove it if I want to. I used a piece of velcro to attach it. I have used it for many months and it works perfectly.
