This is a remix of @BryanWilliams's nozzle holder since theirs didn't fit with the seemingly bigger silicone sock of the hotends I got. Additionally I added some extra space to add the little metal clip that comes with each hotend as the original one didn't have space for it and putting it under the silicone sock without the thermistor is a pain.
To get the clip in you just drop it in the hole before the nozzle and let it slide into the little compartment at the side. To get it back out you simply turn the holder upside down and let it fall out, though you gotta make sure to place a finger over the screws and second nozzle so those don't fall out ;)
The box in the pictures has a height of 7u (including the base), but I also uploaded an 8u version that should allow for stacking even with everything in place.
If you wanna make some adjustments or even use the dynamic Gridfinity base I used, check out this OnShape document!
