2020 Spool Holder - Top mount (with or without bearings)

Was thinking about making the upright hollowed in some way to save filament? please let me know what you think.

Final update (maybe...) - redesigned from scratch with solidworks... now it should print smoother and be a little better looking... added a "non bearing" model aswell...
Print laying flat with the mounting foot piece sticking up...

Print with supports under the bearing shafts (they are floating by a few mm) to eliminate mushroom foot then they should require almost no cleanup...
