I've got slightly addicted to making stacking storage drawers out of my old spools - however like most people I've got a mishmash of spool manufacturers lying around. 

I LOVE the following two spool storage systems:

and

I'll admit I prefer how the stack/spin system runs for the Sunlu drawers - so I basically adapted the link-doughnut part that goes between those drawers so I can stack both an e-Sun spool onto a Sunlu spool without it ending up as PLA and spool Jenga. I haven't done a cardboard to cardboard stacker piece yet and it's not the most finessed bit of 3D design, but I'll take any storage I can these days! 

Excuse the terrible photo - I was making it for my own use and uploading in case it's of use to someone else out there.
