Modular Filament Spool Holder (Different sizes)

thingiverse

This is my interpretation for modular filament spool holder, my issue was that pretty much all filament holders had to be hung on the wall and you cound't put it on table or shelf. Also spools have different sizes so I made this one modular and universal for all types. Love to hear feedback and to improve this and other designs :) If you need different sizes let me know.
