Summary
Overall, the prototype works well. There are a few flaws, such as not having the amount of floss we planned to insert (50 yds) due to a technical error with the 3D printer, as well as our inability to wrap the floss as tightly and efficiently as a machine could (so it would fit inside of the handle). We also found that people had trouble cutting the floss, some because the floss would slip underneath the cutter, others because it would not catch on the edge of the cutter and would therefore either fray the floss rather than cut it, or not cut at all and leave people pulling more and more to no avail. These are problems that we have thought of solutions for, but cannot be added to our prototype presently.
