Dry Box Bulkhead Assembly

I needed a drybox to feed soluble material from for the MMU 2.0 upgrade on my Prusa I3 Mk3. There are other designs out there but I wanted to try improving on them.

As of now, this is a work in progress I'll know more after using the MMU with it a few times.

Feel free to ask questions.

UPDATE #1 (11/7/2018)
This has been working well for 4-5 prints using the Prusa MMU 2.0. I originally designed it for 3 materials and tested it with 2 spools of PLA but currently just have one spool of soluble material in there.
