Filament Spool Holder

Derived from http://www.thingiverse.com/thing:148454

I liked the original design but couldn't find the right metric parts locally, so I reworked the design to use imperial parts that I could get cheaply from my local hardware store. Also changed it slightly so that both cone wedges are identical.

Update: added printable mounting clips
Update: added generic mounting brackets (mounted a second spool on the shelf of my desk)
