Filament clips for different size spools

A remix of http://www.thingiverse.com/thing:2221206 clip set:
Sometimes it was not obvious which clip I used for which spool, so I had to stack the clips next to each other to find the right size. These are labeled on the side, so you always know which size you used. Also added few smaller clips, for thin-walled spools.

Update: intermediate sizes 0.5, 1.5, and 2.5 are added.
