Small hinges for your various projects, my use happens to be attaching an elevator to my RC plane. They will need some filing with an emory board to make them pivot freely cuz I was lazy and did't make extra clearance, but it only takes a few seconds. Then just stick a paperclip in there and bend the ends to keep it in place. Parts A and B are different heights for slightly different thicknesses I had to work with, part C is the opposing side.

Use a short layer height for high detail as these have small holes, and no need to crank up the speeds they will print great in like 20 min.
