Roof Filament Spool Holder M8 rod

Filament Spool Holder for mounting to the roof. 2 sizes, one large that fits everything and one smaller for smaller rolls. There is also a clip to increase the carrying capacity and lock it in place. If you want symmetry you can mirror them in your slicer. 

Would recommend thick boarders and a lot of infill. Print at 0.3 height.

Easy to swap filament and goes well together with with this bearing:
