spool stand one piece design

this was 1st really useful design I did.....much stronger than needed fill at 20% or less.

It was designed for 1Kg spools would work with anything that size or smaller. I set it on floor below my printer but have also used it from beside the printer with spool on bookshelf.

I did not include the rod...it was a piece of scrap anodized aluminum that was laying around... would suggest that a dowel or broom stick cut off would be just as usefull. if wanted I can add the rods caps and even design a printable rod.
