Spool hub for the Heavy Duty Filament spool for mendel

Some time back I printed off the Heavy Duty filament spool (http://www.thingiverse.com/thing:11447) and love it. It keeps my filament out of the way mounted to my printer. However my recent batches of filament are coming on spools already but I don't want to mess with any other form of filament system. The solution was a hub that is compatible with the mount (http://www.thingiverse.com/thing:10254) of the filament spool system but is designed to hold the new spools.
Spool has a center hole 76m
