PrintrBot Filament Holder Clip

I decided to place my Printrbot in a heated chamber which requires the Filament Spool to be on the outside. I designed this clip to help guide the filiment. I need the printerbot to be mobile so I need to keep the printrbot spool holder in place. The clip is very easy to remove.

I am a newbie to 3D printing and I am loving the Printrbot Simple Metal. Thought I would try to contribute. Hope this helps someone.
