JMG123's remix of Airtight filament delivery system

thingiverse

This is a remix of Stephenmhall's "Airtight Filament Delivery System (Almost)" Not that there was anything wrong with the original, I just had an excess of 3mm hex bolts lying around, and no 4mm's that the original needed. I also wanted to have the filament coming out of the side rather than the top so that it is easily stackable. I designed a bracket to hold an offcut of old broom handle in the middle of the box. The spools sit on this rather than the base of the box. It also allows me to use my loose filament spinner, which takes 5m,10m or 15m wraps of trial filaments. The internal filament bracket can take some sponge for filament cleaning. The whole thing was assembled with M3 hex bolts, and a little bit of silicone glue to make sure it all remains airtight. Finally there is also an end cap that takes the 4mm pneumatic connectors to blank off the ends.
