PIN-header connector housing

WARNING! this is a very complicated print, it requires sanding and cutting and gluing when mounting (how much obviously depends on the quality of your printer). Be prepared to do a couple of tries with different settings and put some work to the printed parts before you get it working.

This is an experiment to see if it is possible to print a working connector using 2.54mm pitch pin-header 2x2 female and male. I've been using pin headers in a lot of experiments so I figures it would be fun to make them look a bit nicer. I will use this connector for a project where an Arduino controls temperature, ventilation and light in my 3D printer cabinet.

I've printed most tests using 0.05mm layer height and the threads work very well, at first they usually snag a bit so you have to work it back and forth gently until they run smooth. I tried several different methods for locking, like flexing pieces on the side that you push in order to release, but the material wasn't up for the job and
