compilation of ideas... I sliced open a new small rubber hose I had left over from replacing the wiper motor in my BMW for the trim. I saw other cups made but always thought there was a potential of cutting their tongues on the home made ones.
Solution = hotglue + hose 8)
Screened the back and voila! Done~
