Spool ramp

Previously, we designed the Makerbot Deluxe Filament Spindle MK1 (available at http://www.thingiverse.com/thing:3116), but soon noticed that the full filament roll would slide off the sides and either jam the spool or wrap around the shaft beneath it, causing feeding difficulties. After some quick CAD work and printing four parts, we found a solution that keeps the filament in place. We haven't had any issues since. To install these parts, print them and then apply double-sided tape (we used 3M high bond tape) to each corner of the spool, making sure it is close but not touching, rotating the spool once to prevent jamming.
