Removable Spool Arm for Lulzbot Mini 3D Printer

This is a modification of the original Lulzbot Arm, to create a removable arm that slides into a bracket (http://www.thingiverse.com/thing:756064) on the right side of the frame. This clears out the right side opening on the frame to allow for easy insertion of the panel for an enclosure (http://www.thingiverse.com/thing:756211).
This mod simply cuts off the hinge portion of the stock arm, and tapers the end.

As a side benefit the modified arm will print on the bed of the Lulzbot
