Bowden in-line filter (parametric)

Update 7/29/2017 - Sorry - just noticed I had an old SCAD file uploaded - corrected this...

I wanted a filter to put on my bowden feed - but I also wanted to be able to swap out which filament I was using from my drybox (which has 4 outputs) - so I made this...I use a short PTFE tube from my drybox to this filter and a constant one from the filter to my extruder.

Threads are "pre-cut" by the ISOThread library - for my printer, this was very rough but was easy to clean them up with my tap.
