Filament Spool Holder

The spool mount on the back of the Ultimaker 3 wasn't long enough to hold wide spools, so I needed something that would hold wide spools.

I tried to make this as simple as possible to print. I have been using this for the past couple years and it works really well. The only thing I would change would maybe be the design for the filament guide. It works well, but I think it could be slightly better.

Print the shaft rotated 90 degrees vertically so that you don't need support material.

I also included the .blend file for anyone who wants to tweak the original design in Blender 3D.
