Printrbot Simple Metal Z-axis Filament Guide

Got inspired by http://www.thingiverse.com/thing:601038, but thought the fastening screws were a bit overkill since its only purpose is to guide the filament. So I designed a similar one, but without screw holes and with less material. The holes do fit a tube I have lying around, will attach it later.

On the bed in the pictures you can also see user Aistaca's other thing http://www.thingiverse.com/thing:601004 waiting to be assembled.
