Dry Box Bulkhead Assembly

thingiverse

I needed a drybox to feed soluble material into for the MMU 2.0 upgrade on my Prusa I3 Mk3. Other designs exist, but I wanted to try improving 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. Originally designed for 3 materials, tested with 2 spools of PLA, but currently just have one spool of soluble material in there. UPDATE #2 (5/8/2019) Added a Single Version.
