One thought on “Final_proj#3

  1. You mentioned that it takes about an hour to mold 1 droplet, and you plan to build 100. How far into that 100-hour build are you? This is one of those things that can and should be calculated early on. You might want to scale back a bit from 100 droplets if the time is indeed an hour each.
