Basicly what I have worked on so far is just making a CAD design for the band. I printed the first one off with PLA and it was looking good but pretty bulky. after that I designed a new band which was looking a lot more slimmer and lighter and stylish. the issue with that I am thinking though is that a rigid band is going to introduce so much issues for our study which is why im thinking of second guessing my design. also I started a littler bit with the pcb.
