Yet Another Printable Spool

Printable spool equivalent in size to MakerBot Filament Spool.

I only have one spool and the rest of my filament is a pain in the neck.
Until I have used this up, I need a filament spool or two that fit on Charles Pax's MakerBot Filament Spool Holder.

I'm sure there are plenty of good spools out on Thingiverse already, and I'm sure I should reference half of them as inspirational to this one. I couldn't find one that was a direct replacement for the MakerBot spool, which is what I wanted.
