Cardboard spool cap

Cap to (hopefully) keep your spindle from ruining your cardboard spool.

I made a cardboard spool (http://www.thingiverse.com/thing:1550) a few weeks ago. I finally got tired enough of hand-feeding filament (and occasionally ruining a part as the z platform was pulled off the nuts by filament tension) to suspend my spool over the Makerbot.
