Filament dispenser box

Introduction
==========

There are many filament spool holders available, with numerous geometries and types. However, all I tried so far worked with loose spools that I had to juggle around when switching filament. I wanted a simple system which serves as filament storage and allows easy access to the filament for use.

The idea as such is not new, there are similar designs available. This solution uses regular containers available at your local hardware store and a cheap plastic pipe. Additionally some pneumatic quick connectors, Teflon tube, M4 screws and zip ties are used.

My 3D printer is placed in an Ikea box with the filament dispensers on top. A feedthrough with an additional Teflon tube brings the filament inside. So far it's been working great.
