Changed the hole of spool axis in order not to be any possibility of friction with the screw.
For those who are printing in high temperatures and enclosure, is better to print all parts with PETG. And also the guide holder must be printed with supports.
Also changed the filament guide (I think that's the final filament guide)
It fits all kind of spools, from 250gr to 1kgr (at least all that I tried with different diameters and width)..
Changed almost everything, made some clearances to print at top height without extruder touches the guide and brackets, Tested many guides to post this one. Also added washers to axis to spin more freely. Hope you enjoy it. I'll leave it for a while in editing mode in order to test little more and get some feedback from you.

Another on frame spool holder for Bear Upgrade and also for 20x40 aluminum extrusion, with ball bearings 608zz.
You will need
4x 608zz ball bearings
2x M8x130 (or longer)
2xM8 hex nuts
It is 30mm diameter and for spools width<=87mm (overall axis length 100mm)
