Ender 2 Pro Spool Holder

Once installed, my printer went nowhere, so I no longer needed the handle attachment.
Creality made a big fuss about its small footprint. So I decided to shrink that even more.
This is an edit of my design I uploaded on www.printables.com.
I reinforced the back by increasing its thickness and adding a support bracer in the middle.
The reason is I discovered that a full 1kg spool of filament would cause the holder to bend a bit.
It will still take a 80mm spool without issue.
A trick I learned from another channel is to wrap PTFE tape around the bar for smooth rolling action.
I might modify it later to use ball bearings for added smooth function.
