Lulz Mini Rounded Spool Arm

This is a rework of the original Lulzbot Mini spool arm. All I did was take the original design and add a smooth rounded nose for the spool to sit on. I also tweaked the stops on either end since my mod added some height. Quick and easy if you don't want to go with a spindle or an alternate mounting system. You could also wrap the now-rounded edge in some teflon tape to make it silky smooth.

You don't need any supports...the curve is small enough to eliminate that hassle.
