aeberbach JNS remix semi-threaded

Remix of "Jigsaw nozzle storage blocks for M6-size 3D print nozzles", I made a slight modification in the thread, so its a semi-threaded entry, that way you can press the nozzle until a point where a manual or slight threading can keep it in place.

The pictures added are from a Prusa Mini print, with 0.25mm nozzle in 0.1mm detail profile. I'm confident this works too with a 0.4mm nozzle.
