Spool Spacer / Holder for Ender3 and CR-10

Works with Ender3, CR-10 and many more.
Step-up your print quality with even filament distribution.
No more wobble on the spool holder.
These simple spool spacers just print in 2.5 hrs.
Fitts spools from ColorFabb, Filamentum and others.
Takes the uneven diameter between sides into account with second model slightly smaller (marked: small).
I use them for over a year now. Works like a charm so I decided to publish it.
