where to get small, empty spools?

I occasionally purchase small amounts of loose filament for colored accent pieces I add to larger prints. That means I'm collecting a bunch of filament that I'd like to have on a spool, but all I have are the typical spools for 1kg of material.

Anyone know where to get small empty spools? Something the size of the spool for the sample blue included with the R1 would be fantastic but I can't find them on ebay...

Thanks.

That's the spool holder, not the spool itself

 

I guess I could... do you know of a free design somewhere?

 

There's a spool there you can print out to hold loose filament

Here is a spool on thingiverse all I did was type in "spool" and this popped up but I saw more but this should work for you. Hope this helps. Thingiverse http://www.thingiverse.com/thing:7980

Thanks for the link. All I ever noticed before were the spool holders, not the spools.
