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 You need no other screws. Just print it and use it.

Ender can print from left side of printer without filament guide. When I am changing colors, I am also changing spool position. I am always printing from first (left) position on spoolholder. But it depends on your spool type. Or how much filament you have on spool.

After messing with dual color printer I made bigger version. There is more room for filament spools, and you can have extruders below spool.

Happy printing guys.

And dont forget to like and post makes. Thanks.

Update 29. 12. 2019: Added slightly wider and taller version and now it fits all my spools. It still fits on Ender-3 bed. I removed original design so now its only V2 and bigger spoolholder.
