Elegoo Centauri Carbon Spool Holder

I did not like the tiny diameter spool holder that comes stock with the Elegoo Centauri Carbon 3D printer. The spool would always hang very low and I had some issues with spool of filament moving away from the side of the printer and then having loops wrap around the backside. My printer is perfectly level, so I did not expect this to happen. It turns out after closer inspection that the spool holder is just a bit titled from the weight of the spool (I have many hundreds of hours on the printer - with zero printing issues except for having to babysit the filament). So, I created a larger 45mm diameter spool holder. It just inserts like the stock one, using a 3/4 turn lock.

I printed this with the Elegoo CC1 with High Speed Matte PETG, 30% infill. I also used TREE supports. Print it upright with the large end on the bed (not how the CAD picture shows it!)
