I have personally cut a piece of a plastic tube taken from a pen! Led can be fit inside there beautifully. Use a piece of about 2 cm and paint it black. I have opened a hole at the front side of the box and i glued this plastic tube at the internal space of the box. This is for to protect the tube from knocking when you use it. Fix the IR led at the bottom of the tube, and now the light needs to go in a straight line for to reach the sensor.
