Original Prusa i3 Mk2 spool holder

A very simple spool holder.
Two 608 ball bearings,
one piece of 8mm threaded rod
4 bolds
two washers
one piece of 5cm PVC pipe

insert ball bearings into two 3D printed parts,
Then glue the parts into the PVC pipe

And that's it
It's the exact diameter of Joseph Prusa's rolls.
I should have to adapt something for bigger diam spools...

Added now two feet for enclosure support of the roll : https://www.thingiverse.com/thing:2513203
