Spool hub for the Heavy Duty Filament spool for mendel

thingiverse

Some time ago I printed off the Heavy Duty filament spool (http://www.thingiverse.com/thing:11447) and truly enjoy using it, keeping my filament neatly mounted to my printer at all times. Lately however, my recent batches of filament have come on spools by themselves, but I am not looking to tamper with any other kind of filament system in place. To find a suitable solution I searched for a hub that would be compatible with the mount (http://www.thingiverse.com/thing:10254) of the existing filament spool system and was designed specifically to hold these new types of spools. Unfortunately, the center hole on my spool measures 76mm in diameter but it is too thick for the standard mounting mechanism. As a result, I decided to print out two hubs that would fit around the center of the spool on each side and used bolts to securely hold them into place through its core. I had initially planned to upgrade my printer and was getting ready to get this project printed out to test it, but my current upgrade plan has run into unforeseen setbacks so far.
