Nozzle Holder Case Ultra

This is a printable nozzle holder case that can hold up to 20 nozzles, for the man or woman that has lots of nozzles.
This is inspired off of the E3D Nozzle Holder by 3D previews.

FEATURES:

Holds up to 20 nozzles.
Indented separator between the top 10 and bottom 10 nozzles, with the idea you can store your regular brass nozzles and your specialty nozzles (such as hardened steel or vanadium) separately.
Has a sliding cover that locks into place magnetically to keep your nozzles safe.
Nozzles screw into the holder with an appropriate thread and will not fall out.
Has an optional multi-material (MMU) compatible design for the cover.
Has an optional Slice Engineering™ Nozzle Wrench holder which also magnetically locks into place.

Note: Slice Engineering Nozzle Wrench only works with Slice Engineering nozzles. I highly recommend their nozzles.
