Stackable Filament Spool paint organizer

I recently found this awesome print (https://www.prusaprinters.org/prints/30894-filament-spool-paint-organizer-25-kg) where you can turn your old 2.3 kg spools to a great paint organiser.

I love this print, but I have way more than just 28 colors and also plenty off old spools laying around. So I created a simple base, where you can add the spool so that it spins easy enough as well as an extension where you can then add additional spools on top of the other one.

For the first spool print one "Base" and 4 x "quarter-holder-extrudr-vallejo". For each additional spool print 1 x "Extension" and 4 x "quarter-holder-extrudr-vallejo".
