This is a universal spool roller for spools of diameter 200mm and up.


Print two copies of the base.

Add for each :
4x F624zz bearing
2x M4x25 bolt
2x M4 nut
4x M4 washer

File the inner surfaces where the bearing will be loacted.
File the bolt holes with needle file. Don't force drill them, they snap easily.
Pair up the flanged bearings with the flanges out.
Assemble the bearings inside the slots using a bolt by placing a washer at each surface mating with the plastic.
Tighten by hand or gently using a screwdriver.

The foremost copy in the attached photo shows the first iteration where the supports are smaller than the ball bearings' flange. This was too fragile and broke off when re-drilling the bolt holes to size. The final version in the background has larger supports.

Having tried ones like this and ones that connect the two rollers I much prefer the ones that connect the rollers. Allowing them to slide just doesn't work as well IMHO, but it does lock you into a particular width, which is a problem if you get your filament from different places.

murat - in reply to cymon

I noticed that, with spools that are lightweight, once they are almost empty, there isn't enough filament weight to counter the coiling of the filament to keep the spool on tracks. I am considering an adjustable set with some means to keep the spool down...
