New SpoolHolder (Remix of Butchja's "Universal Filament Spool Holder") in the works

I really liked the spool holder I was using (which was a remix of Skrutt84's "Filament Holder Deluxe") but I did not like the very pointed threads.  Nothing wrong with them and they held up fine, but they just bothered me.  I also gave mine away to a buddy who was having some issues with his filament feeding (I rarely use my spool holder on the Ender 3 now that I have dry boxes with built in rollers).  So when I saw Butchja's "Universal Filament Spool Holder" I wanted to give it a try.  However, since I previously remixed Skrutt84's Spool Holder Deluxe to use a pre-cut 5/16 x 6" threaded rod, I wanted to have the same setup for the new one.  The benefit of this design is that it will be an easy and cheap no-cutting option for folks who find it harder to obtain metric threaded rods.  The pics above are what I came up with, and if it works out, I will post it up to Thingiverse soon.  It will require the following parts:

1x 5/16"-18 x 6" threaded rod (I will be using a threaded stud)
2x 5/16" lock nut
2x 5/16 x 11/16 OD washers
2x 608ZZ (skate) bearings
