Doughnut cutter

I don't know whether my favorite geeky foody, Alton Brown, would love this for the precision and simplicity, or dismiss it as a unitasker, but I like it. :) His doughnut recipe called for a specific size for both inner and outer cutter rings, and states that it is important. On that Saturday morning, I did not have one. So, for one of my first prints ever, I made this doughnut cutter per Alton's specifications.
