Enhancements for Simple spool system for a Mendel (or other 3d printer)

I have changed the design by making a reprappable base for the spool. This way you don't have to mess around with wood for the base, just print it!

UPDATE:
I have added a spool_clip part file, also parametric and designed in OpenSCAD. Just print 6 of these little guys and they will clip right into the slots on the filament spindle parts to enhance the length. No other pieces are needed.
