Simple spool mount for Taz

Most of my parts are pretty short, so I don't mind mounting the spool a little lower on my Taz (but i haven't had any problems even with prints around 120mm in height)

This works well because it's so short: the forces the spool exerts on it are so close to where it sits on the Taz frame, that there's no way it can fall over.

The slight arch on the bottom deflects just enough to push out into the frame a little more, and the bumps on the top keep the spools in the center.

I recommend ABS for this, as PLA might deflect over time?
