Fold Down Spool holder

Yes another spool holder,
but this one can be stored when not in use, and not take up much space.

For mechanical strength, there is a hollow channel inside,
giving 4 'solid' walls, giving a massive strength to weight (plastic cost).


Images, show my up Robot digg extruder,
I have included my newest version, ** recommend 100% fill.
Enjoy
