simple holder for e3d v6 nozzles with M6x1 threads.
5 nozzles per size (2 rows of 5 for .40), each size is labeled and at the bottom put labels to keep regular brass nozzles and hardened nozzles separated.
Larger has 10 rows from .15 through 1.0 nozzles with labels for regular brass and hardened
Multiple smaller - with varying row counts and nozzle sizes.
You can do 2 color by changing filament after layer 4.0
I have included STEP files that have all versions so you can customize further or eliminate sizes you may not need/want.
I will be uploading other versions of the small holder with less rows of filament once they are done
2 perimeters Color change at 4.2 mm. 2nd color - Atomic Translucent UV reactive Pearlescent Neon Green
