Filament Roller for Ender 3V2

This model uses bearings in the center to allow for easier rotation for filament spools, especially cardboard rolls like Overture's. I made it specifically for my Ender 3V2 so it can use the same locking mechanism but I think it would work on other printers as well. 

Printing parameters:

I used 25% infill I believe and it seems to work but you could mess around with that

I also used like 4 perimeters to make sure they're nice and strong

Supports will also be needed for the connector part

It is worth noting you need to make sure you print these things with some beefy settings, especially the center rod to make sure it doesn't just snap off under the weight of the entire filament roll lol
