I was looking for a efficient spool cradle/holder for my various spools for storage, no need to roll freely, just simple holder to keep Spool in place for easy storage and retrieval in future. 

Found Chris Schroeder's design https://pinshape.com/items/203... , I feel it is compact and what I was looking for.

I lengthened it (my biggest spool is around 100mm wide, reduced the overall volume to save on filament, since I plan on printing multiple copies of it to store my filament spools

It should be a relatively straightforward print with no supports required, print as is.
