My first attempt at making a one-print moving part.
I found it works well at 0.2mm layer height. It'll take some moving to finally break it free but it does open all the way up eventually with a bit of working.
Use standard settings for whatever material you are using, although I have only tested this in PLA.
Use supports everywhere unless you can do amazing overhangs ;)
