Rail attachment that doesn't exist, but should?
I just started my final undergrad semester of mechanical engineering and have to do a capstone project in which I design and build a novel product.
Given how universal rails are, I'm interested in designing a new rail attachment that would fulfill a need and be marketable.
So I come to you all to solicit suggestions. What doesn't currently exist that you'd like to see exist?
It needs to be something useful, something people would buy, and something that could be designed, built, and tested in one semester (around 13 weeks). I have to decide on the idea fairly quickly.
So, what's something new you'd like to attach to your rails?
