The nozzle case needs two pieces of filament for the hinges. The main hinge that joins the lid and bottom of the box is 35mm. The latch hinge requires a piece of filament that is 20.20mm in length. I went slightly longer on both of mine so I could melt the tips a little to keep the filament from slipping out. I've included both .stl files and .3mf files. Also, there are 2 different style lids, 1 has the different size nozzles labelled on the inside and the other is blank.
