Dual spool holder for Ender-3 (and other printers with 2020 profile)

I wanted to have more spools on printer, when I am printing dual color medals. So I looked at my MK3 spool holder, and made a simple dual spool holder for my Ender-3.

Its simple to print, and works very well. Spool holder can carry big 1 Kg spools (like ones from PM Filament, Prusament etc. That green one is 1,1 Kg spool from 3Dactive.pl).

**No supports needed.** Just **3 perimeters** and some infill and you are good to go.

Its designed for original screws from ender spool holder, so *
