About this 3D model

I was getting affected by ABS fumes so spent a bit of time looking for a good/cheap [activated carbon](http://en.wikipedia.org/wiki/Activated_carbon) air filter. I decided on [this automotive one](http://www.ebay.com.au/itm/281009061923?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649) for under US$8. The only downside was it was bigger than my print bed. So I needed a holder and something to mount a fan on, and I needed to chop it up to fit on my 155x155 (6") printbed. So here is the full model and the four cut-up STLs along with the OpenSCAD file. Designed for the above filter and a 120mm fan. Generally parametric so you can build your own if needed. This was the genesis for my FanLib OpenSCAD Library, see it [here](http://www.thingiverse.com/thing:111187), you will need it if you want to edit it, change fan sizes, or adapt to another filter size. p.s. should also do as a soldering filter, but not tested yet. I've been using this for many months and it has prevented my previous nose/sinus issues. Very happy with results.
