Angled Bolt-on Filament Spool Holder Makerbot2

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/cLn97zWdiLe

This spool holder bolts on to the front corner of a Makerbot Replicator 2 using the existing bolt. It's angled about 5 degrees to keep any filament spool from slipping off. Works well when paired with http://www.thingiverse.com/thing:1602164 as a filament tube guide.
