A "One Size For All" (almost?) Spool Roller, using 624zz bearings.

As I have now three size of spools, I finally rejoined the meme of using two separate bases in order to fit any width of spool :)


Print two.
Add for each :
4 624zz bearing
2 M4x25 bolt
2 M4 nut
4 M4 washer

For the 603 model use M3 bolt/nut/washer instead

For the 623zz model use :
2 M3x20 bolt
2 M3 nut

Wouldn't be enough two bearings for each base? I've seen lot of designs with only 2 bearings or even with printed tubes instead, it should work here. It would be a thiner part and you know, the less vitamins, the better ;) Very smart solution by the way, so simple and so effective!
And, for those who ask about connecting the parts, why would you do that? keeping them separated is the main point of this design, and thingiverse is full of already connected bases designs (thing: 46016, 283656, 236875...)

Yes, probably :)
(but I had some spools, repurposed from a Stratasys printer, with quite large flanges)

Are there any limitations to the weight these spools can take?

for the commons spools it should work without problems (biggest I had was 2.3kg) and probably more

ok, thanks

I just made one and printed tubes to connect them. All I had where longer M4 screws so the tubes fit over them nicely and also had the ends made to fit over the M4 locking nuts.

I could imagine them perfectly for our PLA on http://www.igo3d.comwww.igo3d.com!

to align and fix them you could still take desired length treaded rods.

The weight of the spool if sufficient to keep everything in place :)
