Parametric Filament Spool - Adjustable Hooks

I order most of my filament from Faberdashery. It is supply only as a bundle of material rather then on a spool. The other issue is that the 100m lengths are of a different diameter then the shorter lengths.

I printed out the filament spool as one of my first prints but rarely use it.

Then I cam across the Hobby Clamps http://www.thingiverse.com/thing:12616 with their method of holding the clamps in place.

That led me to designed these adjustable hooks that can move anywhere on the arms
