Spool holder with bearings

EDIT April, 27 2018 : after using it for days, the arm is bending due to spool weight, i uploaded a stiffer version of the arm --> Arm (renforced).stl
Maybe an other option would be to print it in less bendable material.

As the tornado comes without spool holder, i needed to print one. I wanted a solid and bearing spool holder to screw on aluminium profile or control box directly so i made this one :)

Even if i've done this for the Tornado, it's compatible with all printers of course !

Hope you will like it !

(look the assembly video below before)

You can secure tight the second nylon nut but don't tight too much the third one or the spool holder won't turn freely.
Let a little play.
