Simple Filament spool stand v2 - 6cm spacer

The original Simple Filament spool stand v2 by [FablabMoebius](http://www.thingiverse.com/FablabMoebius/about) has seen more use than any other thing I have printed. The name says it all really, it's simple, and my spools just stand perfectly in it. To get my 3D Prima rolls to site I also had to print off a 6.5cm spacer which I found from [SeanSu](http://www.thingiverse.com/SeanSu/about) [here](http://www.thingiverse.com/thing:358366). I liked the extra support I go from the triangular lip too.
