Centered Top Mount Spool Holder for Geeetech A30 and CR-10 style printers.

This is a top-mounted spool holder for 2020 extrusion that uses parts from the original Geeetech A30 spool holder and a few wheels like those found on the bed or axis gantries.

I wanted a simple spool holder with bearings that was centered above the printer for use with a direct drive extruder, and was simple to mount and use. This is what I came up with using spare parts I had laying around.
