This is a remix of the Filament Spool HDD Bearing Adapter created by Peaberry (https://www.thingiverse.com/thing:2052951) to be used with Peaberry's top mount spool holder bracket (http://www.thingiverse.com/thing:2054533).
I needed a hub adapters for filament spools with a 51mm & 57mm ID hubs. The remixed hubs have the same 25mm diameter hole for the HDD bearing and similar in overall size as the original.
Also when trying to re-purpose a broken 1TB Seagate HDD, I realized the HDD bearing design was quite different from the one used with Peaberry's Filament Spool HDD Bearing Adapter. My HDD bearing was press-fit directly to the HDD housing and wasn't mounted on a separate mount plate.
So I designed a HDD Bearing Adapter Plate as well to fit into Peaberry's top mount spool holder bracket design and use with my remixed hub adapters. The Adapter Plate fits snug into the top mount spool holder bracket center hole. I didn't have to screw it down.
