Hi
I really liked the way the spool was on my previous printer (Turnigy Fabrikator) so I designed this little part...
Here's what you need
2 spool holder like this one https://www.thingiverse.com/thing:928600
2 print of the provided "top spool holder.stl" here
4 Allen Screw M420
4 square aluminum tube 1010443mm (drill a d4 hole @ 10mm from the end)
1 aluminum tube d10504mm

That's it :-)

Should be strong enough to hold 2 pieces of 1kg filament spool...if not I'll redesign one for a 12mm alum tube....
