Bowden Clip Filter Box

After [remixing](https://www.thingiverse.com/thing:2943284) this [filament guide](https://www.thingiverse.com/thing:1776779) to accept a bowden clip, I decided to take it a step further and design a filter to go on the other end of the tube. I used egg crate foam and the filament slides through it nicely while sweeping off misc debris. It's a nice compliment to my remix of the original filament guide.
