Safety: don't make this using 3D printing. It will break. I never tested this. I haven't even tested the entrance angle. It is designed to accept a standard 5 mm brake ferrule (I think). I might make a version that accepts a barrel adjuster in the future (for modeling purposes only). Probably not unless I get interest. Designed to fit using 4 mm bolt for a seat post clamp.
