Parametric Loose Filament Spool Holder

A remake of Tech3Design's handy holder for loose filament samples, but as an openscad design, so you can make one the right size for your samples (my rigid.ink samples are a bit too small for the original one). Same nifty pivoting hook design to make it easy to put the sample on the holder.

Included .stl file that is the right size for rigid.ink samples, and enabled Customizer to make your own.

NOTE: I haven't yet printed this one to confirm the fit of the swivelling clips! Hence WIP.
