Roller stands for the anti-vibration filament holder. This roller stand will pivot on the center bar and absorb vibrations from the inertia. The superstructure will stabilize quicker and the remaining energy will disperse with the rocking motion of this platform. The concept was taken from earthquake vibration arresting technology used in high-rise bldgs. Place this item on the mounting stand without any screws or fasteners it should be well secured but able to rock back and forth. If you use a cover to keep the filament dry- (none included here) then make a hole the same size as the one on the bottom here and place the cover between this holder and the base.

you will need 2 x 8 mm shafts and some 30 mm grooved wheels for the bearing for the rollers. I then used pencil erasers for the shaft to cushion them in the holder.
