Side-Release Buckle - Pin & Ladder Lock - 24 mm - fully printable

It's a buckle with quick side opening and with Pin-Lock or Ladder-Lock for 24mm wide straps.

The predecessor model uses an M3 screw as a pin and an M3 nut as a mating thread Replacement Buckle for 24mm wide loop Strap with M3 screw as a retaining pin for seabag. That looks robust and it is. However, I thought that it should also work without specially machined parts.

This buckle is now completely printable and the idea of the Pin-Lock type was to make the insertable pin printable as well.
