I just redesigned the whole thing and all I got was 1 area improvement. the previous design was so much prettier. :(( This is the third time I'm writing my notes for my final submission. I feel like I could shave another 40 cost off of this given enough time. combining the arms for the final movement of the output and removing one from the silver rod side. I just realised I could have probably saved on cost by removing the final tracks... why didn't I think of that earlier...
