Spool Shelf for Ender3 V2

I wanted a shelf support for the filament spool. I made this to fit over the spool stand that ships with the Ender3 V2. I recommend printing the shelf part with supports and then using a narrow modeler's chisel to clean out the support sprue. I used a quick drying cyanoacrylate cement to secure the arena with the shelf.

From the photos, you can see that the spool rides on this spool roller:
