Notes:

I recommend a brim for the SpoolholderUpper.stl and SpoolholderLower.stl

I updated the design for the new CoreOne MMU3.

I integrated a slit for the lables from: https://www.printables.com/model/50348-prusa-mmu-belegung/fileshttps://www.printables.com/model/50348-prusa-mmu-belegung/files

I usede the combined spoolholder from: https://www.printables.com/model/26079-doubled-brackets-for-improved-mmu-spoolholderhttps://www.printables.com/model/26079-doubled-brackets-for-improved-mmu-spoolholder

Post-Printing

Mounting the stand and back.

The SpoolholderStand and SpoolholderBack parts fit together by friction. I added 2 mm holes so you can secure the connection with tiny screws, if you want. Be careful when you stick together the stand and back parts, because the back part breaks easily.

How I Designed This

The reason why I created this

The new MultiMaterial spool holders have a tendency on long prints to loose the axels from the bearings. So I designed the SpoolholderUpper.stl to prevent the separation. Then I realized that I can minimize the space, needed for the 5 spools, so I created the rack. You need 6x SpoolholderStand.stl and 3 x SpoolholderBack.stl and 8x SpoolholderUpper.stl and 12x SpoolholderLower.stl.

I've included the SketchUp file, so you can improve on my design.

Happy printing
