Filament Spindle - 1 lb or 5 lb

First off, I have not made or tested this. The dimensions etc are based on lessons learned from Poor Mans Quick Change Spindle thing 3855 which I did make and am currently using. I would prefer something slick looking like MakerBots spindle, so hopefully they will sell it or something.

This modification of MakerBots filament spindle allows quick change for 1 lb coils of plastic. 1 lb coils slip on and off easily without unscrewing anything. This is handy for me since I have half dozen colors
