Spool Holder for makerbot

I got tired of the spool holder that came with my Makerbot Replicator 2 so I made this one with Fusion 360. printable without supports on its side. I am uploading 2 versions, one slightly shorter with the center hallowed out to cut down on the filament usage by 2g. These are much easier to get the spool on/off than the pinch one that came with the printer.
